Well, it looks like you're about halfway to where you're gonna have to
start improving your hardware / using slony read slaves / using
memcached or something like that to handle the extra load. Keep an
eye on your wait%. If that starts climbing and vmstat shows more and
more bo going to your drives, then you'll need to improve your I/O
subsystem to keep up with the load.
