We are at approx 100 queries per second in prime time. The load on the server is low and the performance is OK (haven't tried anything else but FreeBSD so I can't compare with Linux). Everything is working fine until a single thread suddenly locks up the entire system. :( There are no special compile options for neither FreeBSD or for MySQL (from ports).
