Sorry about that, I remembered as soon as I sent it that I hadn't
included version. It's x86_64 version 2.2 (did a conary updateall from
2.1 beta. Uname -r gives 2.6.17.14-0.3.smp.x86_64.
I'll try with a UP kernel although it will take some time as I have to
rebuild the e1000 module from the UP kernel sources.
Try without the network trunking anyway in the meantime. Would be an
interesting test.

I'll let you know
if I can reproduce on the UP kernel.
I don't think it's related to that ticket as they are all writes anyway
and they only see the problem on large files.

Hi Dave,
Excellent test and bug report.
I wonder whether it may be related to this:
https://project.openfiler.com/tracker/ticket/435
Can you try to reproduce with a UP kernel pls.
Also I need the output of `uname -r`
Thx,
R.
FTR: this is running r58 from IET svn

Hi All
I think I've found a bug in the iscsi target software in my
benchmarking/testing.
Some background on the hardware first in case it may be related.
Dual core/dual opteron with 2GB of ram
3ware 8006 2 port raid card for OS drives
3ware 9550SX card for data drives
Dual GB Broadcom on-board NIC's teamed into bond0 (management)
Quad port Intel PCI-E GB NIC with all 4 ports teamed into bond1 (main
iscsi data network)
4 x 250GB WD SATA HDD's in RAID5
Of note here is that I have had to replace the e1000 driver with the
latest from Intel to support the quad port card
I have made some volumes and mounted them on various windows servers
and
have been using iobench to tune performance of the system. When using
a
read only test pattern I see this

Doing write only based patterns this doesn't come up. After this
performance of the system dives (from about 110MB/sec of iscsi
performance to about 10MB/sec).
This is fairly reproducible here so if you need anymore information
just
ask.
