Those aren't terribly impressive numbers. With that many spindles and that
much cpu, you ought to be getting double or triple the performance I see
below, no?
I'm attaching numbers from one of my servers. It happened to be a bit busy
at the time (it's the company's mail server among a few other tasks). Specs
are:
Dual PIII-450
256mb RAM
2 Adaptec 2949U2W controllers (one for OS, one for RAID)
1 x 9gig barracuda for the OS
4 x 50gb barracudas + 1 spare in RAID 5 config
[ritz@fridge ritz]$ bonnie -s 512
