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. ============================================================================ = -Chris Watson (316) 326-3862 | FreeBSD Consultant, FreeBSD Geek Work: scanner@jurai.net | Open Systems Inc., Wellington, Kansas Home: scanner@deceptively.shady.org | http://open-systems.net ============================================================================ = WINDOWS: "Where do you want to go today?"
