Dear all,

Can somebody tell me that why the Redhat AS4 running very fast if compare to Fedora Core?

Is it because of the kernel size?
If I recompile my kernel (take uneccessary driver or module), is it possible achive same performance as RHAS4?

And, can I know which distro have the performance same with the RHAS4 but less headache for driver in laptop?

Regards

My personal opinion so far (as a gentoo user), is that setting up the right GCC flags and optimizing it for your specific processor, as well as compiling the kernel yourself and/or modifing and choosing by hand your kernel drivers does make the computer faster.

When I had mandrake 10.1, I compilled the kernel in (DON'T LAUGH!) 30 minutes... Now with gentoo with the 2.6.12 kernel, I compile it in 8 minutes. (extra modules and experimental drivers compiled with that)

However, Gentoo is more difficult as far as drivers goes. The fast and (easy?) distro you are probably looking for is Arch.

Fedora Core is kinda/sorta an experimental distro. Fedora Core 4 didn't fit my linux, performance and stability needs.

So, I'd recompile my kernel. However the performance still same. And, i'd do some some hdparm tweaking seems like no difference?

I'd try this in suse10, fc5

Does the size of the compiled kernel matter? Is it very important?

Which range of sizes would be recommendable for a desktop PC?

kstan:
If you recompile with the same configuration, you will still have a long kernel compile and lots of unused drivers.

Don't compile everything built in, that will make a huge kernel.

SlackTRAXX:
I never tried to fill a kernel with every driver and option out there, I don't recommand it either.

For a desktop PC, most distros make most drivers as modules, since they can load on demand, and are quite conviniant.

Yes I do have take out all uneeded driver and protocol (like atm, apple and etc).

However, the performance still remain (During Login I found Redhat as4 much faster than FC5)
Any other place to tweaking?

Try to remove useless init scripts, or try out initng.
Try to modularize as much the drivers you don't need all the time.
Try to remove useless startup applications in kde/gnome...
