is it worth compiling my own kernel

hi,
I have recently started using winex to play games in linux, finally freeing
myself from the reboot to windows to play games. I heard it mentioned that
compiling your own kernel can produce performance gains, and I was
wondering how significant these would be? Also wondering how difficult it
is - I have a bunderstandinganing of linux (write very simple shell
scripts, practiced in compling and installing software, use the console
lots), but the whole idea seems intimidating!

By the way - I'm running mandrake 9.2 with KDE 3.2, nvidia Ti4200 128MB
graphics card, 256MB RAM, Athlon 2000 @ 2000MHz and the cvs version of
winex (till I have tested it to get the majority of games working!).

thanks

Building your own kernel does two things.  (Assuming you choose the right
options)  It compiles the kernel specifically for your chip.  And you can
strip out all of the default features that you may never need or use.  I
almost always build my own kernel.  Perfomance gains can be significant,
if you know a little about what you're doing.

Many distros default to an i386 compilation.  Which basically means it's
optimized for a 386.  If history serves, that would be mostly 16 bit
machine code.  Many newer chips have 64 bit code available, while
maintaining reverse compatibility down to 8 bit code.  

So a custom kernal can make use of 32 and 64 bit modes that are available.
 This can double and quadruple the speed.  Bearing in mind that most newer
machines are more limited by the amount of ram and drive speeds than CPU
speed.  You can sometimes triple the speed of a machine just by doubling
the memory.

Although for games, video acceleration is probably more of a plus than the
bit code of the kernel.  And gobs of memory couldn't hurt.

Definitely try building your own kernel. If it doesn't work out, keep
reading. But before you do that, I seioursly recommend you upgrade your
RAM to at least 512, that will provide the most significant performance
increase (apart from getting a new video card).
