> Patching zfs_prefetch_disable = 1 has helped
It's my belief this mainly aids scanning metadata. my testing with rsync and yours with find (and seen with du & ; zpool iostat -v 1 ) pans this out.. mainly tracked in bug 6437054 vdev_cache: wise up or die http://www.opensolaris.org/jive/thread.jspa?messageID=42212 so to link your code, it might help, but if one ran a clean down the tree, it would hurt compile times.
