In the same machine as the previous test set, but with 2.6.38 (debian
squeeze backports kernel):
NCQ 1, two drives both connected to 3726 behind the **88SE9123**
(previous mail was for the 88SE9125):
# while true ; do sh -c "(hdparm -t /dev/sdb & hdparm -t /dev/sdc) 2>&1
| grep MB" ; done
Timing buffered disk reads: 190 MB in 3.02 seconds = 62.97 MB/sec
190 MB in 3.02 seconds = 62.99 MB/sec
Timing buffered disk reads: 194 MB in 3.02 seconds = 64.27 MB/sec
194 MB in 3.02 seconds = 64.24 MB/sec
Timing buffered disk reads: 192 MB in 3.01 seconds = 63.87 MB/sec
194 MB in 3.01 seconds = 64.44 MB/sec
Timing buffered disk reads: 194 MB in 3.02 seconds = 64.26 MB/sec
194 MB in 3.02 seconds = 64.23 MB/sec
Timing buffered disk reads: 194 MB in 3.02 seconds = 64.14 MB/sec
194 MB in 3.03 seconds = 64.13 MB/sec
Timing buffered disk reads: 194 MB in 3.02 seconds = 64.31 MB/sec
194 MB in 3.02 seconds = 64.18 MB/sec
Timing buffered disk reads: 194 MB in 3.02 seconds = 64.31 MB/sec
194 MB in 3.02 seconds = 64.15 MB/sec
Timing buffered disk reads: 192 MB in 3.01 seconds = 63.73 MB/sec
196 MB in 3.02 seconds = 64.87 MB/sec
Timing buffered disk reads: 194 MB in 3.02 seconds = 64.16 MB/sec
194 MB in 3.02 seconds = 64.27 MB/sec
Timing buffered disk reads: 192 MB in 3.01 seconds = 63.72 MB/sec
196 MB in 3.02 seconds = 64.83 MB/sec
Timing buffered disk reads: 194 MB in 3.01 seconds = 64.47 MB/sec
192 MB in 3.01 seconds = 63.79 MB/sec
... so it works, but is about 50% slower than the 88SE9125...
change NCQ depth to 31:
# while true ; do sh -c "(hdparm -t /dev/sdb & hdparm -t /dev/sdc) 2>&1
| grep MB" ; done
[after a considerable pause:]
Timing buffered disk reads: 382 MB in 3.01 seconds = 127.10 MB/sec
... i.e. one drive results only, the other read failed, with this in dmesg:
