We really, really need to move the database back to a machine with a
decent hard drive. The wikis are very sluggish, and a fair chunk of
it's from waiting on the database.
Ursula's sitting around with a 90% idle CPU, but everything's blocked
on disk I/O to the point it's got a load average of about 16. At any
given time from 8-20 processes are blocked and waiting. Operations that
hit a lot of rows like history and watchlist are particularly badly hit
since they don't play as well with caching.
If Geoffrin's not going to be up soon, and Pliny's still emitting
spurious disk errors, what are our options out of the available
machines?
