Hi!

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.
