This will take quite some clobbering of the AL though. And is supposedly also dependent on the adapter / firmware in use.

My heavy I/O was a buildworld with /usr/src and /usr/obj each on their own FC disk, both on the same loop. >Fix: mjacob has sysctl changes sitting in the pipeline to allow retry tuning for the da(4) driver. Adding delay hysteresis (Matt's words) in the isp driver is also called for. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
