A second processor might be a good investment here. Of course, two
servers is also worth considering, as such a setup is likely to be, at
least, more robust in the face of hardware failures. (It's also more
complex...)

Possibly, yes. MySQL is threaded, and the OpenBSD threads implementation
isn't the fastest possible (it's all in userland, so there's only one
kernel-level process/thread).

If using a better database (PostgreSQL comes to mind) is not an option,
you might want to consider using another system - like FreeBSD - for
this; MySQL performance isn't terribly good, even on a uniprocessor
system, anyway.

This does, of course, not mean that it is unusable by any means; many
people run MySQL on OpenBSD and are quite happy with performance,
stability, and so on. Me, I dislike MySQL for other reasons.
