Linux supernova 2.6.17-gentoo-r8 #1 SMP Sat Dec 9 16:38:02 EST 2006 sparc64 sun4u TI UltraSparc II (BlackBird) GNU/Linux
Right now I'm using 4 disks on a single channel of an NetFinity EXP300 / Adaptec 39160 in Linux software RAID-5. I had planned to fill up the EXP300 and use both channels of the enclosure and RAID controller but I'm already running into bottlenecks with just the 4 drives I have caddies for now.
Single disk performs as expected:
| Code: | supernova ~ # hdparm -t /dev/sdc
/dev/sdc:
Timing O_DIRECT disk reads: 104 MB in 3.03 seconds = 34.36 MB/sec |
MD array however performs very poorly:
| Code: | supernova ~ # hdparm -t /dev/md0
/dev/md0:
Timing O_DIRECT disk reads: 178 MB in 3.01 seconds = 59.11 MB/sec |
Should be more like 120MB/sec, no?
The following seems to indicate that absolutely no IRQ load-balancing is occuring and the system does not seem to change behavior with
different values of /proc/irq/*/smp_affinity. "top" also reports only a single CPU logging time in system interrupt state and system state when
the RAID volume is being tested.
