network performance tuning
by fedora 02 Feb '04

02 Feb '04

As I have mentioned before I am working on creating various Fedora server loads at http://www.packetstorm.org/fedprj/ So far I have the core load done and I am almost done with the log server load http://www.packetstorm.org/fedprj/core/log_server.htm While looking into network performance tuning options, I ran across the following setting tweaks that could be made on the system net.ipv4.tcp_rmem = 10000000 10000000 10000000, sets min/default/max TCP read buffer, default 4096 87380 174760 net.ipv4.tcp_wmem = 10000000 10000000 10000000, sets min/pressure/max TCP write buffer, default 4096 16384 131072 net.ipv4.tcp_mem = 10000000 10000000 10000000, sets min/pressure/max TCP buffer space, default 31744 32256 32768 net.ipv4.tcp_sack=0 turn SACK support off, default on net.ipv4.tcp_window_scaling = 0, turn TCP window scaling support off, default onnet.core.hot_list_length = 300000, maximum number of skb-heads to be cached, default 128 net.ipv4.tcp_max_tw_buckets = 2000000, sets TCP time-wait buckets pool size, default 180000 net.ipv4.tcp_timestamps=0 turns TCP timestamp support off, default on net.core.rmem_max=524287 maximum receive socket buffer size net.core.wmem_max=524287 maximum send socket buffer size net.core.rmem_default=524287 default receive socket buffer size net.core.wmem_default=524287 default send socket buffer size net.core.optmem_max=524287 maximum amount of option memory buffers, default 10240 net.core.netdev_max_backlog=300000 number of unprocessed input packets before kernel starts dropping them, default 300 For the log server I focused on socket buffers as I noticed that udp packets were getting dumped due to high syslog volume. But does anyone here have a really good explanation on the settings above? Can they be used as a general performance tweak on any system configuration? I read in one place some of these settings should not be used on multi-user systems. Is there a Fedora tuning guide? Any recommendations for a good baseline? Is there a reasoning behind the default Fedora settings listed above? Not that I disagree but that I want to understand it. FYI here is a SPEC doc I found in google where some of these settings were mentioned http://216.239.41.104/search?q=cache:JrEBIcPgWoIJ:www.specbench.org/web99/r… thanks Greg

dulug.duke.edu mirror

Anyone else noticed that this rsync mirror isn't deleting packages when it syncs with Fedora development? Seems to now have 2-4 versions of the same package instead of deleting the older ones.

Kernel build problem

Fewer partitions are better (Re: Disk Layout/Partitioning Practices)
by Keith Lofstrom 02 Feb '04

02 Feb '04

Ron Herardian <rherardi(a)gssnet.com> writes: > When installing everything and allowing for future updates and packages > I am using the following disk layout: ... 7 partitions listed ... It may be time to rethink multiple partitions. For legacy reasons, I build my systems with multiple partitions, but if I had it to do over again I would probably do it with 3 partitions: /boot (because it has to be small) swap (about 2 GB) / (everything else, including multiple drives if LVM) For the average system, the swap probably should be smaller, but I run huge, poorly designed CAD apps for days that tend to fill VM. With RAM so damned cheap these days, I agree with other folks that make swap a lot smaller than 2x physical RAM. Paging more than a few hundred megabytes of swap is just too damned slow, regardless of the amount of RAM that you happen to have in your system. If I had a problem with users writing huge files that filled the disk, I would put quotas on the individual users, not on their partition as a whole. If anything goes wild, and fills up /, the system is in trouble anyway, and repair time is not significantly improved by limiting the fillup to one of many partitions. In fact, a lot of problems happen because /tmp fills, or /var/mail fills and /var/log doesn't work. I subscribe to the Andrew Carnegie maxim "Put all your eggs in one basket - then WATCH THAT BASKET". My past excuses for multiple partitions were: (1) limited disk sizes and (2) managing backup tapes. Both are invalid now. With large drives and LVM, there is no practical limit on partition sizes for most systems. With disk-to-disk random access backup, there is no need for complicated partition arrangements to fit data onto small, slow tapes. I control backup frequencies and depth by directory, not by partition. On mild excuse for retaining multiple partitions is to minimize boot time - if you are running a journalling file system, it will occasionally delay booting for significant time to fsck one or two of the partitions. But if you have a very large /home, the time saved by peeling off a bunch of smaller partitions is not that significant. There are probably better ways to schedule fsck. I expect strong opinions differing from the above; no doubt I've forgotten something. Newbies should keep following this thread and see where I've erred. But a lot of the reasons we do things are traditions that stem from past restrictions that no longer apply. We should acknowledge these changes in our system designs.

Link 2 computers thanks to a "crossed" network cable
by Coume - Lubox.com 02 Feb '04

02 Feb '04

Hello, I have been using Fedora Core 1 since it came out, but there is still one thing that I cannot manage to get working :( I cannot manage to create a network between my linux laptop and another computer under windows (or linux). It was working fine with Mandrake :( I'm able to log onto the university network and then access the Internet. BUT if I connect my laptop directly to another computer thanks to a "crossed" network cable, I cannot get the computers to "speak" together. Is one of you managed to plug 2 computers like that??
