I would be appreciate if you could tell me which processer family to choose,My processer is P6200,is close to core2,but there's some diffierence,and I want the optimization to be the best.And I'm about compliering the kernel,
the needed infomation is as below,and my chooses are so many:

The P6200 is based on a first-gen Core i, so use Core2/newer Xeon.

ask your compiler what it thinks would be the best, as root run :

Thanks,I will give it a try!
The output of the command:
Gentoo-11 / # cc -march=native -E -v - </dev/null 2>&1 | grep cc1
/usr/libexec/gcc/i686-pc-linux-gnu/4.5.2/cc1 -E -quiet -v - -D_FORTIFY_SOURCE=2 -march=core2 -mcx16 -msahf -mpopcnt --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=3072 -mtune=core2
Thanks again!

You should really use a 64-bit kernel for that CPU, even with a 32-bit userspace.
