Over a pretty quiet Gigabit link, 3x 10k SCSI disks, all on the same
controller, in a RAIDZ pool exported using shareiscsi:

Hi John;
This is a know bug of MS. You need to do a few tricks to optimize the
performance on windows clients.
I have attached a file where you will find a easy method to optimize
windows
clients.
Let me know the results.

Hello All-
I've been creating iSCSI targets on the following two boxes:
- Sun Ultra 40 M2 with eight 10K SATA disks
- Sun x2200 M2, with two 15K RPM SAS drives
Both were running build 82
I'm creating a zfs volume, and sharing it with zfs set shareiscsi=on
poolname/volume. I can access the iSCSI

is terribly slow, as in five megabytes per second sustained transfers.

It would be useful if people here who have used iSCSI on top of ZFS
could share their performance experiences. It is very easy to waste a
lot of time trying to realize unrealistic expectations. Hopefully
iSCSI on top of ZFS normally manages to transfer much more than
5MB/second!
