I started using apache with mod_wsgi, and now it's fast! So this
indicates it's a problem that only occurs when using rocket or
cherrypy, but again I'm only measuring it with firebug in my browser.
I have 768MB of ram, ~500MB free. I use cron for @reboot only.
I only run it on a remote machine (on slicehost VPS). I do not think
it is network problems because it is fast in my web browser until I
get hit by a bunch of users. Of course I'd like to eliminate the
network from my measurements, but for that I need webserver processing-
time logs.
