A couple of questions for you:
(1) What OS are you running (Solaris, BSD, MacOS X, etc)?
(2) What's your config? In particular, are any of the partitions
on the same disk?
(3) Are you copying a few big files or lots of small ones?
(4) Have you measured UFS-to-UFS and ZFS-to-ZFS performance on the
same platform? That'd be useful data...
