Then I think the best performance option would be a swap partition on a
separate hard drive. Run some tests on the drive to see where it's sweet spot
is in relation to access speed, probably the beginning of the drive, but not
If it is the only partition on the drive, changing the size would be trivial.
You could even have a small swap file on the main drive so you still have swap
available while you play with the testing. You could probably find a used but
small fast scsi drive on ebay fairly cheap. I sometimes see 36 gig drives for
$20 US because they are to small for the original users purposes.
