Make that 4 or 8 GB total. We have seen a huge boost in performance when
we upgraded from 4 to 8 GB. Make sure to use a decent 64bit Linux.

Three options:
9500-4LP with Raptor drives 10k rpm, raid 1 + raid 1
9500-8LP with Raptor drives 10k rpm, raid 10 + raid 1
Go for SCSI (LSI Megaraid or ICP Vortex) and take 10k drives
BBU option is always nice.

Bjoern
