Well, when I run lots of queries, sometimes they take a few milliseconds
longer. I think it has to do with my disk wearing out.

Seriously, if you want a detailed explanation you're going to have tell us
exactly what queries you are executing. I have a database up for 3 weeks and
it's just as fast now as when I started it.

What's intensive? 1 per second? Oh, you know about vacuum and vacuum
analyse, right?
