Seems that the performance is indeed atrocious. I recently (like 2 days ago) had to rescue my zfs pool under opensolaris to spare disks. The performance under OpenSol was what I was expecting, 70MB/s reading and writing at the same time.
Now that I'm restoring the stuff back under FreeBSD 8.0-p2 it seems that first the array reads from the source disk and then stops reading and decides to empty the buffer to the destination. There's usually a 2 second pause and after that it goes back to reading. There seems to be something really wrong with this, fbsd zfs implementation seems to be unable to move data between 2 zfs pools writing and reading simultaneously... I think I'll just boot back to opensol and do the transfers there. -- br, Tommi _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
