I was hoping for something better than 500M/minute. I'm sure there are any number of factors that are slowing things down. It seemed like incorporating the larger blocks/boundary alignment might help. I'm testing it now and I'm not sure I'm seeing it. -- Paul Beard / www.paulbeard.org/ _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "[email protected]"
