I know the numbers look ok, but we are definetly suffering. Also, if I try to
run any sort of vacuum or other db activity during normal business hours,
load goes through the roof. I have seen loads of over 10 when trying to
vacuum the larger cluster and would have to kill the vacuums due to
complaints.

I think this is probably related to the hardware configuration, but I want to
make sure that there are no changes I could make configuration wise to the db
that might lighten the problem.
I'm especially want to make sure that I have the memory parameters set to good
numbers for my db's so that I can minimize thrashing between the postgres
memory pools and the hard drive. I am thinking that this may be a big issue
here?
Thanks for any help,
Chris
