I'm not arguing with what you say.  I'm agreeing.  Once you need locks
and such MySQL is slow.  It only does full table locks, I think.

I have a single user production application on which MySQL flies and
postgres merely runs.  But if I were to build a multiuser hig volume
web production system I wouldn't use it either.
