I find the RAID5 on the PERC to be painfully slow.  It's _really_ bad
if you don't put WAL on its own drive.

Also, you don't mention it, but check to make sure you're getting ECC
memory on these boxes.  Random memory errors which go undetected will
make you very unhappy.  ECC lowers (but doesn't eliminate,
apparently) your chances.
