Greetings,
when I upgraded from Fedora 12 to Fedora 14, about twenty days ago, the system (which wasn't doing really well even before the upgrade) became almost unusable. The problem is, very likely, upstream of Fedora, but I would like to understand where exactly is and if/how Fedora in some way amplifies it. I've posted all details here:

Adrian,
I understand the rationale for this suggestion. The reason why I haven't done this (yet) is that (see above and in the article) I already had ALL the same problems, just a bit smaller, with FC12, which was a clean install, with all updates applied etc etc.
In other words, the situation with FC12 was just barely tolerable, with the upgrade it simply degraded more.
I am trying to gather as much info as possible to understand what is the fastest, or at least "more likely to succeed with the smallest number of reinstalls" way forward. For sure, I can't go on like this, and I will be forced to reformat/reinstall from scratch if I don't find a solution.
But at that point, I'll directly try another distro first, simply because my feeling right now is that a clean install of FC14 (or 15) wouldn't do much. One of the reasons why I took the time to make an article online about this is the hope to find somebody that says "hey, I have the same hardware as you, and it runs real fast with distro XYZ"

Weird problems often have a hardware issue behind them. There are many things to check. Some are easier than others:
From the desktop, open the program System>Administration>Disk Utility.
Select each of your hard drives in the list on the left, and then click the Smart Data button.
In the upper part of the window, look for a Bad Sector count, and Overall Assessment of the drive.
Any problems?

I have noi Disk Utility under System->Administration. What is its real name?

The program is actually found in Gnome at: Applications/System Tools/Disk Utility

Sounds to me like your X setup
"Probably, a good part of the problem is in some weird X/nVidia/kernel interaction, or lack thereof, but can it really justify this behavior? Opening and closing windows and tabs, typing text… this is stuff that even with a suboptimal or misconfigured driver should be instantaneous. No?"
The answer if your X is all messed up may well be not, although if you set your X server to use the VESA driver with shadowfb you might get a better idea, as there I would expect it to be acceptable (but not great) regardless of card.
There are lots of other things it could be, unfortunately you've not provided any really useful information on the machine, you've not provided any dumps of stuff that would be useful, not even running top, or mentioning whether it is better after a reboot and so on, no dmesg data, no X logs nothing.
So start with a reality check. You have a complex system that is misbehaving, to debug it sanely you need to do it step by step and you need to actually know little details like which X server is being run, whether it is the same one you were running in FC12 and so on.
On an 8GB box with Intel onboard video even Gnome is usable so something is definitely wrong in your specific setup

I have now, in comments to the article. I certainly did not expect to get the complete answer in one step (as I wrote at the end of that page), I wrote everything I thought useful in that page. And I had put "little details like which X server is being run" in that page since the beginning, in the form I thought it could be enough, ie attaching the installed RPM packages. And I also _acknowledged_ right there that it couldn't be enough "so please tell me what other inputs do you need, thanks".

exactly my point :-) I am sure a big part of the problem is Firefox+Flash, but can that be the WHOLE problem? As I wrote in the article, it's not like killing Firefox (while it does improve things) solves everything.
Dmesg output is pasted below. Boot, reboot or not it makes no difference. let it go ten minutes, and it starts behaving like that.
Thanks again for your quick support! Just ask for more tests if needed.

This along with nspluginwrapper & the flash player from adobe are some culprits I see causing trouble :( I guess I am lucky to not get some of your troubles.
You may also want to post output of # tail -f /var/log/messages
to see if something else is there. Also check how many ``services'' that are needed are running at boot time.
Regards,
Antonio

I have now, in comments to the article. I certainly did not expect to get the complete answer in one step (as I wrote at the end of that page), I wrote everything I thought useful in that page. And I had put "little details like which X server is being run" in that page since the beginning, in the form I thought it could be enough, ie attaching the installed RPM packages. And I also _acknowledged_ right there that it couldn't be enough "so please tell me what other inputs do you need, thanks".
On an 8GB box with Intel onboard video even Gnome is usable so something is definitely wrong in your specific setup
exactly my point :-) I am sure a big part of the problem is Firefox+Flash, but can that be the WHOLE problem? As I wrote in the article, it's not like killing Firefox (while it does improve things) solves everything.
Dmesg output is pasted below. Boot, reboot or not it makes no difference. let it go ten minutes, and it starts behaving like that.
Thanks again for your quick support! Just ask for more tests if needed.

That is something I hadn't thought of.
What devices are connected to your system?
Perhaps a Linux driver, for a device is having problems. Perhaps a device is generating lots of interrupts.
Can you disconnect any devices and see if the slowness goes away?

besides hard drive and DVD burner there are only Logitech webcam, wheelmouse and earphone microphone, but everything is plugged in the back which is not really accessible without moving furniture. I'll do that if needed, but isn't a way to check for those interrupts from the prompt?

Let's see if iowaits are you issue. Install the sysstat package (yum install sysstat) and run: iostat -x 1
(this gives extended information on the disk, and updates at one second intervals)
The number to look at is 'await' times, expressed in milliseconds. If those numbers are high, it's something with your drive.
Also, if you run 'top' what does it show?
I saw an F13 system brought to its knees due to a WD EADS series 'green' drive triggering insane awaits of multiple thousands of milliseconds, and system load averages in excess of 20. The command that reliably triggered the behavior was a simple 'yum update' from the command line, or the automatic packagekit update process; load averages went through the roof, and the system slowed to a slow crawl.
Replaced the WD EADS series drive with a Seagate of the same capacity, and the problem went away. Now, in this specific case, the EADS drive was one half of a RAID-1 mirror, where the other half was a Seagate; the EADS drives and RAID don't get along. But others have reported performance issues with these drives not in a RAID configuration, with recent kernels; older kernels seemed to work better.
I'd check that even though the WD2500JS-41MVB1 drive is a 'Caviar Blue' and not a Green drive.

here it is, thanks for the tip. When it isn't zero, the await column gives anything from 27.36 to 35.78 (last line) to 5 (I have already posted top output in a comment to the web page):

Sorry, of course that's only the part of the story about sda. here is one complete run of iostat:

Could you show the output of iostat -x 1, not iostat -x 1 | egrep -i 'device|sda' please?
On my system, when I do iostat -x 1 I get "avg-cpu" besides drive information. avg-cpu: %user %nice %system %iowait %steal %idle 5.05 0.00 4.04 0.00 0.00 90.91
Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00
It might help to see the "avg-cpu". If we are lucky, either the %user or %system or ... will show high cpu usage.

Is there any correlation between avg-cpu %user and Device sda wsec/s writes?
Is there a burst of %user cpu activity followed by a burst of wsec/s writes?
If the system is doing so little, I'd expect less %user cpu activity. Since the system is 2 CPU, does 48% means one cpu ran solid for a second?
Someone help us...I know there is a command to show open files, lsof. Does that command include a way to find out disk activity per file or is there another command that can find out disk activity per file? I'm hoping, if we identify the file(s) with disk activity, we might identify the service/application/kernel feature that is hogging the cpu.

There is the 'iotop' package, which give I/O per process, but doesn't list files.
Both iotop and top can be run in a batch mode with the -b switch; both can run a specified number of iterations with the -n # switch (where # is the number of iterations, infinite by default).
Like many others I'm not seeing this issue; my box being a tad older, a Dell Precision M65 laptop with a 2.16GHz Core2Duo and 4GB of RAM, running the x86_64 dist.

Let's see if iowaits are you issue. Install the sysstat package (yum install sysstat) and run: iostat -x 1
here it is, thanks for the tip. When it isn't zero, the await column gives anything from 27.36 to 35.78 (last line) to 5 (I have already posted top output in a comment to the web page):
[root@polaris ~]# iostat -x 1 | egrep -i 'device|sda'
Sorry, of course that's only the part of the story about sda. here is one complete run of iostat:
Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.00 5.00 0.00 5.00 0.00 64.00 12.80 0.03 6.00 6.00 3.00 dm-0

other runs show all null values for dm-0 / dm-1, or values similar to these
Marco
Could you show the output of iostat -x 1, not iostat -x 1 | egrep -i 'device|sda' please?
On my system, when I do iostat -x 1 I get "avg-cpu" besides drive information. avg-cpu: %user %nice %system %iowait %steal %idle 5.05 0.00 4.04 0.00 0.00 90.91
Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00
It might help to see the "avg-cpu". If we are lucky, either the %user or %system or ... will show high cpu usage.
Another question please...if it's spurious interrupts, I found the device file, /proc/interrupts, which has a row for Spurious interrupts.
We haven't demonstrated the problem is interrupt related. Can we try to isolate or rule out this as a problem please?
Could you show us the output of twice, the second time a few seconds after the first time so we can see if any interrupt number changes fast. more /proc/interrupts ... more /proc/interrupts
Can people suggest any information/files in /proc which might help us?
I assume there is a periodic hardware clock interrupt for your CPU. Can we find out this clock interrupt rate somewhere?

I think the clock interrupt rate is shown by the "Local timer interrupts". I don't know if that number is okay or not. I think it might be okay.
I am curious about the Rescheduling interrupts. I do not have a dual core system so I have no rescheduling interrupts.
I do not know how many rescheduling interrupts is too many.
I did google searches, "Resheduling interrupts" and Linux "Resheduling interrupts" It appears there have been problems, in this area, over the years. We should be careful to limit ourselves to any recent problems.
I found some sort of explanation of rescheduling interrupts at https://help.ubuntu.com/community/ReschedulingInterrupts Also at this URL were suggestions for troubleshooting problems. One suggestion, from this URL was to use "vmstat 1". I haven't used vmstat before so this is educational. Another suggestion was troubleshooting ACPI and APIC problems.
This problem sounds similar to another person's problem: http://www.spinics.net/lists/kvm/msg49558.html I mention this problem because of the date and also it's Debian (not Fedora). We don't know if this person's problem is a "Rescheduling interrupt" problem...but it sounds similar.

A running Firefox, that displays an ordinary News website with several animated GIFs and a couple of Flash ads, here increases the resched.interrupt count by ~100 or more per second. After a few hours of uptime, that will pile up, of course. Marko has quoted the uptime with his "top" output in the blog post. To Marko, you can run
watch -d1 cat /proc/interrupts
in a terminal with and without your mostly used apps running to get a better overview about how the numbers change.
I wonder whether the slowness is specific to running X or only X together with a heavily used Firefox? What other tests have been performed in an attempt to find out whether the system is sluggish in general? Perhaps give "powertop" a try. It reports quite some things about devices that are in use 100% and about stuff that wakes up the cpu often.
In either case, it doesn't sound normal. Certainly not with an average load so low as quoted.

So, for the 2nd cpu, it incremented by 8019 in roughly more than a minute, which is between 100-200 per second. That's also what other people experience without any unusual slowness of the system. Though, when you've stopped Firefox, does the interrupt count still increase so quickly? And with Firefox not being busy anymore (and not processing Flash), are your troubles during typing words and sentences cured or not?
What devices are connected to your system?
Perhaps a Linux driver, for a device is having problems. Perhaps a device is generating lots of interrupts.
In the case of a continual interrupt storm the kernel will detect and log it (and take some attempt at avoiding action).
Can you disconnect any devices and see if the slowness goes away?
Easier to look in /proc/interrupts for stuff going at crazy rates

And I also _acknowledged_ right there that it couldn't be enough "so please tell me what other inputs do you need, thanks".
On an 8GB box with Intel onboard video even Gnome is usable so something is definitely wrong in your specific setup
exactly my point :-) I am sure a big part of the problem is Firefox+Flash, but can that be the WHOLE problem? As I wrote in the article, it's not like killing Firefox (while it does improve things) solves everything.
Dmesg output is pasted below. Boot, reboot or not it makes no difference. let it go ten minutes, and it starts behaving like that.
Thanks again for your quick support! Just ask for more tests if needed.

.....Snip......
I am on F13, with latest updates as of yeaterday. Even when load fact is 0.3 or 0.5, opening most gui applications takes up to 30 seconds and on some occasions, a little more. Applications like OpenOffice, ktorrent, Seamonkey, Amarok...etc. Laptop has 7200 rpm drive (ext3 fs), 2GB ram. This is the case even right after booting. I do recall that things were noticeably quicker to start on much older redhat releases, like redhat 3.0, and even on linux'es prior to redhat. But then the GUI apps at that time might not have been so incredibly bloated as they are today. For an amusing commentary in song, watch http://www.youtube.com/watch?v=d85p7JZXNy8

And that doesn't look good - your flash player is crashing in weird ways. Would make me nervous given that its exposed to remote data and networks. Could just be crap code of course.

And that doesn't look good - your flash player is crashing in weird ways. Would make me nervous given that its exposed to remote data and networks. Could just be crap code of course.

Just to convince us all that it's not some subtle hardware problem, can you make a FC14 live cd and boot from that, and then see if you still get the same terrible performance?

Not right now (can't move from home right now, no blank dvds/cds around). However, I HAD tried a live CD before install (now borrowed from a friend) and it was just as slow, if not slower. Back then I didn't bother too much for slowness, thinking "once installed for real it will go faster", because I only wanted to be sure that it would recognize all the hardware.

You have a very interesting problem.
Given the amount of RAM, and given the result of the top command, from the URL, you are not having a memory to disk swap problem.
May I ask, what is the "purpose" of this system? Is it a server? With the amount of memory, I have no idea how much disk space, and processes running, can I assume it is a server?
If we suspect X/nVidia -and- the system is a server, can we boot in runlevel 3 (i.e., boot without X) to see if the system runs slow?
When was the last time this system was booted?
When the system is initially booted, does the system start slow, or does the system run "fast" for awhile, and then slow down?
Is the system slowing down account specific? Does the system run slow when marco is not logged in? Do you have another account you can log in as?
Is the slowness caused when certain applications are running?
According to the top command, firefox had 24.6% of the CPU, and python and java and another python and httpd and mysqld and ... were all running. Firefox is at the top of the top output.
Can you quit Firefox and make sure Firefox is really stopped. After quitting Firefox, please do killall firefox to make sure. Please do ps aex | grep [f]irefox to make sure firefox is stopped.
I wonder if Firefox is visiting a website that causes Firefox problems. The top output shows Firefox has TIME+ of 96:00.54--I'm not sure the units for 96:00.54, is that 96 minutes, 96 hours, or what? I would like to rule Firefox out, as a possible cause of the slowness.
Can you please boot the system, with the network off? I am curious to see if network traffic is causing the slowness. Perhaps some network service is being attacked from the Internet. I would actually like to see the number of bytes in/out on your interfaces.
I don't know anything about your iptables rules...do they give a hint on network activity? Are services available to the Internet that shouldn't be? If your system is a server, perhaps you are suffering a brute force attack against some service or services. Can you do iptables -L -v Do any iptables rules show unusual byte/packet counts?
I neglected to ask if you checked system logs? Is there anything special in /var/log/messages or /var/log/secure or /var/log/cron or ... I would do a ls -ltr /var/log to see the size of your logs and see which logs are being written to most. I don't run httpd. Where are the log files for httpd kept? Are those log files in /var/log/httpd? I would also check subdirectories of /var/log for log files for services.
The purpose of the above questions is to gather more information. Hopefully, something will stand out that points to the problem.

that's the same thing my wife usually tells herself when looking at me :-)
May I ask, what is the "purpose" of this system? Is it a server?
One reason it has so much memory is that it was my intention to also do some video editing with it (but I haven't gotten to that yet), and re-ordering, geotagging etc, lots of digital pictures. Another is that sometimes, I have to do lots of heavy perl- or shell processing on huge (hundreds of MBytes) amount of text in the background, so I wanted to be sure that this wouldn't slow me down while writing, etc.. Apart from that, this is an "office" computer. Most of the time, the usage is what I already described in the article: web browsing, openoffice, email... The only thing I forgot (sorry) to say there is that sometimes there are other family members leaving their accounts on with Firefox open. They reported the same problems, there's nothing (so far) account-specific.
The firewall is the default FC14 config "no service accessible from outside". output of iptables -L -v is pasted at the bottom. In runlevel 3, things go fine, but I need GUIs here. Firefox IS one big cause of the slowness. It would be interesting to know why the magnitude of the problem increased so much upgrading to FC 14. Turning networking off in runlevel 5 (service network stop) doesn't seem to make a difference, in and by itself.
Oh, and when I said "the system is slow even if firefox isn't running" I meant that I *had* run "killall firefox". I think between this and other earlier messages I have already answered all questions from Rick. If not, please be patient and remember me.
Thanks again, folks!

Impressive reduction in size. And, but do take this with a huge grain of salt, since I'm really tired right now, I just restarted Firefox (I had done killall firefox right before doing this trick), and I also _want_ to see some improvement... it does seem to run faster, at least for now.
Later, and thanks again. Marco

Get BleachBit, and have it install the Administrator mode. Then, with Firefox closed, run BleachBit and have it do all of that stuph for you. The Administrator mode lets you do things that need root access. Personally, I run both just before every reboot on my desktop, but then, I only reboot for kernel updates and only shut down for hardware issues or power failures. Last time I rebooted was after 24 days of uptime since upgrading to Fedora 14. (My sister uses Ubuntu and currently has over 70 days of uptime.)

Though, that'd be a case of bagging Firefox, not Linux. Firefox can be a pig on any computer, especially when preferences are set for long histories and large caches. Firefox has to parse it all, and it doesn't appear to be very efficient at it.
Firefox and Flash are another thing for really sucking up the CPU cycles.

Hmm. I don't recall from the original posting, is this a 64-bit version of LInux? If not, and if you have a LOT of RAM (and assuming you're running a 32-bit PAE kernel) you could be running into a shortage of memory in the lower 3 gigs where the kernel keeps important data structures when doing PAE.

I skimmed your writeup, but didn't look at all of the installed packages.
My environment is much less powerful than yours, and it's pretty reasonable.
Fedora 14 2.6.35.11-83.fc14.i686 2.6 GHz P4 1.5 GB memory Overclocked NVidia 7600 GS with 260.19.36 (built by hand, not rpm) Samsung Synchmaster at 1680x1050 KDE 4.5.5
I run the standard desktop effects. I've tried some of the more esoteric ones, but I find that they're distracting.
I run into some slowdowns. I've commented on my OpenOffice Calc issues. Flash is slow (but it's slow in Windows as well). When I stress test Tomcat/MySQL or Tomcat/Derby applications my load average goes to 11 (literally) while running around 500 transactions per minute.
This sounds like an NVidia driver issue. I suggest wandering over to www.nvnews.net and reading the Linux support forum.
In particular, I have the following set:
nvidia-settings -a PixmapCache=1 nvidia-settings -a InitialPixmapPlacement=2 nvidia-settings -a GlyphCache=1
I've placed these (and my overclocking commands) in a script called nvtweaks.sh. I then have the following line in my .xinitrc file:
/home/mdeggers/bin/nvtweaks.sh
I also have a customized xorg.conf file, and I've modified my fonts (installed MS Core fonts and customized a .fonts.conf file).
This works well for me. Your mileage may vary.
. . . . just my two cents.

Hi, JB. Here is the output of cat /proc/cpuinfo.
tomorrow I'll check the bios setting.
Thanks, Marco

Another idea would be to disable cpu scaling (set the governor on performance) and see how it goes ... its true that having an energy efficient cpu i imagine that you want to keep it at minimum a lot .. look in /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor and change it to performance ... and see how it goes also i would rather recommend conservative governor as scales the freq more slowly that ondemand (less fast and big transitions in freq) btq ... with performance governor MHz should be 2500 ...

AMD's Socket A. Pretty old, slow system. It's possible it doesn't implement APIC and ACPI correctly. Someone suggested a bios update - if there is one, that would be a good idea.
Does the command 'smartctl -a /dev/sda' show any reallocated sectors?

Uh, by /proc/cpuinfo it's a Socket AM2 Athlon 4850e, which isn't too awfully old.
Socket A was pre-Athlon64, and definitely not capable of 8GB of RAM.....
The motherboard he referenced is an ASUS M3N78-EM, which is a current product at NewEgg, among other vendors.

That's a thought.....
Palimpsest (Disk Utility) includes a utility to run SMART tests; launch Disk Utility, select the disk, click on 'SMART Data', then select the test you'd like. It also lists the SMART information from the drive.

when I upgraded from Fedora 12 to Fedora 14, about twenty days ago, the system (which wasn't doing really well even before the upgrade) became almost unusable.
Things went better, then worse, now they are much better, almost good. Short summary: firefox + flash + nvidia = nightmare, while kde/gnome quirks make things more... interesting.
