There's not a lot to go on here, but it sounds like it's possibly an lvm snapshot issue, not an xfs issue, to me. Can you test another filesystem temporarily to see if you see the same slowdown when a snapshot is active? When a snapshot is active, it's doing copy on write, which will slow things down to some degree. -Eric
