Hi all, I've been using RAIDFrame on OpenBSD since 3.1 and in 4 years I've never seen any performance improvement in getting the system to work any faster at rebuilding parity after a hard shutdown. I've tried RAID1, RAID5, SCSI drives, IDE drives, processors from PentiumII 400s to Athlon64 3200+ and it has *always* been ridiculously slow at rebuilding. Just a 9G RAID5 partition takes over 2 hours. A 60G RAID1 takes 11 hours. 11!!! Before flaming me to say, just go and edit the code, it's never been out of beta or whatever, explain why compared to other OSes it's always so slow, even to build the first time around. Linux's code in particular comes to mind.
Cheers, Noth
