Nice. I can use these graphs when making arguments about whether to buy DPT's or other hardware. My only question is have you thought about adding system CPU usage to the graphs? It seems that under most cases CPU cycles are the only thing the DPT's are saving, but I have no idea how many cycles are spent by vinum. cheers, Adrian -- [ adrian@ubergeeks.com -- Ubergeeks Consulting -- http://www.ubergeeks.com/ ] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
