see:

6592835 resilvering is at least 10x too slow
6602697 pool has small write throughput during resilver
http://bugs.opensolaris.org/view_bug.do?bug_id=6722540 -- some mention of the Dirty Time Log
http://blogs.sun.com/ahrens/entry/new_scrub_code
6698575 -- zfs scrub causes multi-second lag over NFS

In particular 6333409 in snv_102 is supposed to speed up
scrub/resilver.

I'm running OpenSolaris 2009.06, and while those are interesting to read, none of them really explain or solve my issues.
