Anyone have one of these raid cards? The disk performance is horrible.
The setup:
ASUS P5Q
kernel 2.6.25-gentoo-r9
Adaptec 3405 Firmware version 5.2-12415 (June 7th 2007)
XFS file systems with LVMS
I have put the mount options "noatime,nobarrier" in one file system but
it made no difference. Any suggestions?
Vernon

xfs is known for its extremly bad defaults when you do your mkfs. If you
search for it on lkml you will find a lot of information.
