Alternatively, throw a lot of memory at the system and point the temp
space at /dev/shm. We've had really good luck doing that here, to avoid
excessive writes to our NVRAM PCIe cards. Make sure the transaction logs
(and any archives) get written to a separate LUN (ideally on a separate
controller) for even more win.
