So at this point we'll order more web servers, but they'll take a couple weeks to arrive. In the meantime I'll profile the web side of things and see if I can't make it faster.
But to help out, go buy a paid account. The fast servers really are worth it. Compare the speed the paidaccounts page loads (always on fast) with, say, this page. If you have a paid account, you always use the fast servers.
