David,
Take a perfstat, and I'd be happy to take a look at look at it, and help if I can.

(System: ONTAP 6.5.5)
We have a Windows 2003 server (SP1) which uses iSCSI to mount a drive onto a NetApps filer.
When transfering files the performance is very poor: it can take 5 minutes to transfer a 350 Mbyte file. Looking at Performance Monitor on Windows while a file transfer is taking place shows that Disk Queue Length readings can reach: Average=94, Maximum=2142
We are using a QLogic QLA4010 Host Bus Adapter with the latest firmware (3.0.0.4) and driver (2.1.0.8).
Any ideas? Thanks in advance.
