FWIW, I just disabled prefetch, and my dedup + zfs recv seems to be running visibly faster (somewhere around 3-5x faster).
echo zfs_prefetch_disable/W0t1 | mdb -kw Anyone else see a result like this? I'm using the "read" bandwidth from the sending pool from "zpool iostat -x 5" to estimate transfer rate, since I assume the write rate would be lower when dedup is working. mike p.s. Note to set it back to the default behavior: echo zfs_prefetch_disable/W0t0 | mdb -kw _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
