Aha. That explains it. You use HW raid. I wondered why you were
only doing 4 million mails for *30* boxes. Dan, is doing 500K, on a
completely idle box (cpu/ram/I/O wise), with vinum, Postfix, and RAID-0.
Have you seen brad knowles papers on vinum vs HW raid? It's erm
enlightening to say the least :) Id be happy to dig up the URL if you are
interested. I personally will be using Vinum from now on. The performance
is very impressive.
