Read the kernel section of the handbook.
Read "man tuning" and "man make.conf", but for a simple beginning, figure out
what tasks you want to benchmark (see "ls /usr/ports/benchmarks"), and get a
baseline with the GENERIC kernel. Then you want to set CPUTYPE, disable the
"cpu I486_CPU" and "cpu I586_CPU" statements, and maybe disable drivers you
don't need, IPv6 (aka "options INET6"), etc.
Be prepared to roll back to a working kernel if you change too much.
Benchmark some more, and see whether you find anything interesting.
Be prepared to have someone tell you to run /usr/src/tools/tools/ministat. :-)
