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. :-) -- -Chuck
