Although PostgreSQL uses multiple processes instead of multiple threads, and that means that (on OpenBSD) PG can scale CPU utilization to all available processors where MySQL can't... if I understand the situation correctly, PG would still benefit from a kernel locking approach that didn't restrict kernel activity to a single CPU core. However, I would be surprised if that starts being a serious problem before OpenBSD's limit of ~4GB on i386 and amd64 started being a problem. And you actually need a fairly big database before that's a problem, so... -- Matthew Weigel hacker unique & idempot . ent
