flatfile databases are definitely not doing your cpu usage any favors. If you think running mysql or postgresql (postgres > mysql in most cases) is too heavy for a little operation like yours, I'm pretty sure you can set up wakaba (or pyib) to use sqlite, which should be lighter.
Anyway, take a look at vpslink if you haven't already. They offer tons of customizability, and it's the cheapest vps you'll find anywhere.
