I'll have to do that on the i386 install tomorrow, as Linuxthreads is not available for FreeBSD/AMD64. >This shows that -current (both SMP and UP) with libpthread is >faster than linuxthreads (different versions of FreeBSD and >mysql, though). For FreeBSD nothing (remote) has been faster than the i386 Linuxthreads test. I'll do everything local tomorrow. >Also, if you use the default mysql config settings, then >FreeBSD remote vs Linuxthreads remote also wins (2685.53 >vs. 2091.10 from earlier post). I understand what you're saying, but those numbers are horrible. >What modifications are you making to /etc/my.cnf and why >do they turn the results around the other way? I used either my-huge.cnf or no config file at all (as noted in the benchmarks). Tell me all the FreeBSD tests you want to see & I'll do them if I can.
