Yep, I see this too.

I can get 80-100Mbyte/sec reads out of a single disk but ZFS is (now) =
very slow - it reads & writes and much more slowly (10-30MB/sec).

When the array was fresh it was nice and fast - it is now 68% full and =
hasn't been much more full than that (I don't know but am pretty sure it =
never reach past 75%).

The frustrating thing is trying to find some way of measuring what's =
actually going on.. I haven't had much luck :(
