Well, there's always /usr/ports/benchmarks. nbench might be what you're looking for -- compile it once using 586/mmx support, and once using k6-3 support. Other than that, time a buildworld/buildkernel. But I'm not a benchmarking person by any means, so this may or may not be accurate. Doing the buildworld/buildkernel will probably be more intensive -- compile it with k6-3 flags, reboot, then do another compile with the same flags. Time that one. Do the whole process again with 586/mmx flags, again, timing the second of the two builds. I don't have a couple of days to throw at benchmarks, so I definitely won't be doing this.
