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 

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 

Thanks for any help,
