Greets All: Sent this to fbsd-geom a few days back but didn't get any response so thought I'd risking your wrath and reposting here since I am specifically interested in fbsd-amd64 context. I shot an inquiry to the gmail address of the sunfire x2100 poster to the amd64- hardware page but didn't get any reply there either. Anyhow, here goes.... I've been using gmirror for quite some while now and it's worked well for me. However, I was curious how it performed in comparison to nVidia onboard raid offerings on various nforce boards that FreeBSD now supports. For example, the fbsd-adm64 mainboard support page links to this dmesg for a Sun X2100: <http://www.freebsd.org/cgi/query-pr.cgi?q=93531>; The part piquing my curiosity being: "The onboard raid is fully functional to me (WD Raptors instead of the stock seagate disks). I made a bonnie test which showed imressive perfomance, but slightly hight CPU usage." Is anyone aware of any benchmarks comparing the nvidia raid1 to gmirror? Or have any additional insights? I don't have a machine free I can test on at the moment but might in next week or two if anyone else is interested. -- Best regards, Ken Gunderson Q: Because it reverses the logical flow of conversation. A: Why is putting a reply at the top of the message frowned upon?
