Hello,

Using CPUTYPE= in make.conf causes the complier to optimize for
the specific CPU. Otherwise, it does a "generic" compile that
would run on any CPU. The two easiest ways to improve system
performance are to build a custom kernel that has all the
uneeded options and devices removed and to tweak make.conf.
Before doing either, read man tuning and man make.conf. Also, to
find out what all the stuff in the kernel conf does, see
/usr/src/sys/i386/conf/NOTES (assuming you're running 5.x on an
Intel or Intel-compatible platform.

hth,

stheg
