Creating new kernel how do i know what cpu to choose when im trying to compile a kernel?

Code:

Quick specs to my box:

that looks like pentium4 based xeonz.

my options:

() 386
() 486
() 586/k5/5x86/6x86/6x86MX
() Pentium-classic
() Pentium-MMX
() Pentium-Pro

Code:

cat /proc/cpuinfo

gives you all information about your cpu. post it here, if you dont know how to interpret it.

what kernel version do you try to compile? from the options it seems a very old version, because no recent cpu is mentioned there. I would recommend a newer version! if you want to stick with it, pentium-pro will probably the best, because its the newest intel... (but so old you wouln't want to run a game server on it).

Im trying to compile 2.6.26.8

then there should be more options (maybe you need to scroll down?)...

If I am not mistaken you have an old netburst / P4-based Xeon, so choose the appropriate option... (I cannot give you the exact name, I have only 64 bit systems running, where completely different options are given)

I scrolled down and found other options (old xeon) .. what is the difference. Would i gain performance from the bottom one?

() 586/k5/5x86/6x86/6x86MX
() bla bla bla bla (p4/old xeon)

Noticed now in some thread the discussion about hpet and tsc i think it was. I have folowed the kernel optimation wiki earlier and first now starting to care about timings
