You can use a much bigger block size, and the job will take significantly less time to run. I have successfully used a blocksize of 512000. Keep it to a multiple of 512. I haven't tried even larger block sizes, but I think they would work fine. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
