> We are currently recommending separate (ZFS) file systems for redo logs. Did you try that? Or did you go straight to a separate UFS file system for redo logs?
I'd answered this directly in email originally. The answer was that yes, I tested using zfs for logpools among a number of disk layouts and performance times were terrible on every one - no better than using a main zpool and carving off /log slices. Performance times went down (good) and disk %busy stayed low on all the ufs/directio setups.
