Hi everbody, I would like to know if someone knows where I can find some guide, tutorial that can help me to improve the performance of Fedora on my laptop in start up.
I think that I need to recompile the kernel and dress it on my computer and remove all unnecessary services. It is true?
Where I can find some additional information??
Thank you very much Bye

Unless the laptop is a toy, I would encrypt either /home or the whole root with home, depending on how you have it set up. Laptops do get lost or stolen, even if you have nothing financial, there are probably things which are no one's business but your own. Mailing addresses, mail people sent you, passwords to mail accounts, maybe social media accounts?
Booting with no services saves time to login prompt, what is time to useful system?
One of the reasons I stick with Fedora is that they have made the effort to make selinux work on the system, something I feel adds a layer of security worth a few seconds at boot. That's my priority, it may not be yours.
But the encryption mechanism is included in SELinux?I don't think so...
There are also some other mechanism to encrypt the HDD independently from the operating system and I think also much more secure...

Pretty sure SELinux has little to nothing to do with encryption. 100% sure you can encrypt mount points with SELinux disabled.

I made three points on fast boot, (1) encryption for security, (2) no services may not be a useful configuration for normal use, and (3) Fedora provides working selinux. After rereading I don't see how I could have been more clear, I put them in separate paragraphs!
I have no idea how you reached this bizarre conclusion, I think the first followup to your post was trying to correct you, but was overly subtl.

Very very nice this guide! Thank you Junk
But if I compile the kernel without all unnecessary drivers and packet, Can I obtain more performance than only disable some service?
Thank you everybody

Disabling services you don't need can speed up boot, and is much easier in the long run than compiling a customized kernel because you only have to do it once.

This might be true, but is it safe? I mean I realize I'm a newbie when it comes to the whole command-line thing and all....but I thought the services that were enabled upon boot-up were necessary? And that if you disable any one of them...you might stand the risk of making your system un-useable!? just wondering is all...

The trick is to find out what each service does before you mask it and make sure you don't need it. If you follow that link I gave you, you'll find that the author explains exactly what each service he's disabling does and why he doesn't need it.

Excellent!...I guess I will make the attempt to (finally!) use the command line and see if I can emerge from the other side without having to re-install F17!... Wish me luck!

OK after reading up a bit more on this I've decided to NOT touch any of the services on this machine. After all it's my "main" machine and I can't afford to risk having anything happen to it. BUT I DO have a "CEntOS" box that I will try thous out on....and if it works as "advertised" I will THEN attempt to do it on this computer. Although I must say, my Fedora laptop is running with a Dual-Core processor and 3GB total of memory, so it's not that bad....the other laptop lon the other hand is running on an OLD Dell Inspirion from Lord Knows when!....so THAT one will be the guinea pig!

Disabling services you don't need can speed up boot, and is much easier in the long run than compiling a customized kernel because you only have to do it once.
I run a self-compiled kernel (3.7.4) on my F17 box, I've removed all the modules I don't need. I did it because I run Gnome on a 1 GB box and need all the memory I can get. I also don't run any services except dbus. Gnome still loads a crapload of stuff that I can't remove. My idle memory usage (in Gnome) is 130 MB.
It boots at exactly the same speed as the Fedora kernel. Disable all the services that you can, and things will boot quicker, but not that much quicker. Systemd does a great job of running startup jobs in parallel. Because I have an encrypted home, boot time doesn't mean a lot, it takes me longer to type the luks password.

Hi!
2013/1/27 carachi diego carachi83@gmail.com
But if I compile the kernel without all unnecessary drivers and packet, Can I obtain more performance than only disable some service?
The Fedora kernel (and actually any other distribution) has most of its kernel options compiled as modules (not drivers). Why? Because it is impossible for Fedora devs to know beforehand the hardware the computer will run and people like to get their hardware up and running as soon as they plug it in.
In any case, the kernel does not load modules on memory until they are needed. So the only thing you are wasting is hard disk space (and not really much). So you could save a few MB of hard drive by compiling your own kernel and removing modules you are not going to use (floppy disks?) but 1) you will spend a lot of time and 2) you may break something.
So my advice is: leave the kernel as is and take a look at unnecessary services at boot.
Greetings,

The biggest change you can make to your laptop to get it to boot faster is throw out the rotating disk and buy an SSD (Solid State Disk). A 120GB disk can be had for under $120. You can cut your boot time from 1+ minute to 15 sec (from the time grub loads to the time the login screen appears). No other change you can make will be anywhere close to that dramatic.
The one fly in the ointment is that you need to have a modern enough laptop for the disk to be a SATA disk. Anything newer than ~2007 should be ok (but check your disk first before ordering an SSD).

This is a pretty big change, but actually my F17 laptop boots fairly quick even with a platter disc. If you look at Lennart's blame game page (already linked) you can save a lot of time by not waiting on services you don't need (not necessarily even disabling them, just not waiting for things that aren't needed during boot).
Yes the SSD is a possible solution to reduce the boot time, but I am in doubt for the writng circle of the SSD because it is very few than a magnetic HDD...
What about load the kernel and operating system on RAM? I see that it is possible load with grub all in memory and if I understand well after the operating system became very faster. Someone try to do that? Maybe increase the time of booting but after you have a very faster computer... What do you thing about this?
Thank you

Just get an Intel 520 series at least twice the size you need and wear out won't be a problem.
The biggest problem is when people fill the SSD to near capacity and the SSD firmware has to do excessive juggling because there aren't enough free blocks. The SSD has to clean a whole write block (~ 1MByte or more) and juggle things around. (keyword: write amplification).

Sounds useful. You'll have to write it though. Slapping in an SSD is simple and doesn't require you to write any home-grown code.
