Hi, I've been testing the new siis driver, and I have found no appreciable performance change, using dd as a measure of "raw" performance. I get about 40MB/s read, and 30MB/s write. See attached bench-*.txt files. Am I expecting too much, or do I have something else going on here? (e.g. dd being a terrible benchmark of disk i/o) Is anyone else seeing better/worse/same numbers? Also I find it surprising that my gmirror read is only 40MB/s, and not 60-80MB/s, any thoughts on this? Thanks! - Derek dd if=/dev/zero of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 0.437049 secs (307099849 bytes/sec) dd if=/dev/zero of=/dev/ad4p2 bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 4.410338 secs (30432527 bytes/sec) dd if=/dev/zero of=/dev/ad6p2 bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 4.401181 secs (30495844 bytes/sec) dd if=/dev/ad6p2 of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 3.234643 secs (41493831 bytes/sec) dd if=/dev/ad4p2 of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 3.689668 secs (41385739 bytes/sec) gmirror label gm0p2 ad4p2 ad6p2 dd if=/dev/mirror/gm0p2 of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 3.331307 secs (40289811 bytes/sec) dd if=/dev/zero of=/dev/mirror/gm0p2 bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 8.167607 secs (16432932 bytes/sec) dd if=/dev/zero of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 0.434279 secs (309058782 bytes/sec) dd if=/dev/zero of=/dev/ada0p2 bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 4.604623 secs (29148472 bytes/sec) dd if=/dev/zero of=/dev/ada1p2 bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 4.402896 secs (30483966 bytes/sec) dd if=/dev/ada1p2 of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 3.203470 secs (41897607 bytes/sec) dd if=/dev/ada0p2 of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 3.211751 secs (41789581 bytes/sec) gmirror label gm0p2 ada0p2 ada1p2 dd if=/dev/mirror/gm0p2 of=/dev/null bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 3.349089 secs (40075890 bytes/sec) dd if=/dev/zero of=/dev/mirror/gm0p2 bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes transferred in 8.121042 secs (16527156 bytes/sec) Copyright (c) 1992-2009 The FreeBSD Project.
