Ok, time to see if JeremyZ will fix some of the Super-Smack compile problems on FreeBSD. About a month ago he said a 1.3 would be coming out very soon. I'll start posting benchmarks from Super-Smack over the network. Super-smack is here btw: http://jeremy.zawodny.com/mysql/super-smack/ If you download it, first thing to do is in client.cc change __FreeBSD to __FreeBSD__ to avoid the ERESTART compile failure. Regardless, I still think my inital MyBench results were an indication of significant performance loss Vs. (Mandrake) Linux no? Even if it is related to the NIC driver, it should be a cause for concern since the test systems and method was exactly the same. - JeremyG
