Hi,
I am seeing extremely poor performance (~100kB/s) when untaring large tar
files into fresh ufs filesystems. I see the problem with softupdates and
without softupdates but with an async mount. This is a Supermicro X7DB8
board, 4GB, 2 x Xeon 5140.
Sample gstat output:
dT: 1.033s w: 1.000s
L(q) ops/s r/s kBps ms/r w/s kBps ms/w %busy Name
585 61 0 0 0.0 61 170 13812.0 100.1| da2
I see ms/w start at about 200ms with a ~3MB/s throughput, and then I see
ms/w rise and kBps drop. ms/w goes as high as 16-20s, and then suddenly
drops back down to about 200ms. Using iostat, while the performance is
high(er), kb/t is 64kB, as the problem starts it drops towards 2kB.
Copying a single large file doesn't exhibit this problem, although
throughput isn't great (~3-5MB/s). However, that's better that 100kB/s.

arcmsr0: [ITHREAD]
There are eight disks connected in a RAID-6 configuration. The
controller's cache is write-through and the disks' write caches are
disabled. NCQ is enabled on the drives.
The same hardware when it ran 6.3-p1 didn't have this problem. However,
the system BIOS was updated at the same time as the operating system (in
an attempt to solve a recent em problem), so it is possible that it is a
BIOS related problem. The same build on an entirely different machine
with an aac controller and SAS disks also doesn't show this problem.
Running 'devinfo -r' doesn't list arcmsr as having an interrupt at all.
(see below). That strikes me as odd; checking another machine that is
still running 6.2 with an arcmsr controller, I can see the interrupt just
fine.
So:
- Does anyone have any suggestions?
- Is it normal for arcmsr to not show an interrupt in the output from
devinfo in 7.1?
Full dmesg, devinfo below.
Thanks,
Jan Mikkelsen
