db-koji01 slowness

Hi!

Well, it was worth a try I think... Sorry to hear it didn't help.

Do the drops increase? What kernel is the machine running?

I tried playing with this a bit yesterday, but it didn't seem to matter
much. ;( 

There is actually not all that much i/o going on. It's mostly cpu and
lots of context switches, etc. 

I guess I will fire off a vacuum analyze (since that shouldn't hurt
anything or cause any problems) and just wait until we are out of
freeze to schedule an outage and try a bunch of the more invasive
things.
