It's crawling - XP takes half an hour to boot, then it's fine. I have yet to measure disk speed (ISCSI disk that is) after boot, but first impressions are that system is up to speed.

I seem to recall that this can happen because the traffic is going via your network gateway into your iscsi target because of some hardwired network setup on XP. You can do a packet trace with wireshark to see if this is your actual problem.

If it indeed is your problem, someone else might be able to chime in with a solution to it.

I also have to remind you that the tg3 driver is extremely slow. You should try to use undionly.kpxe to chainload from the vendor PXE. This gives me quite decent speed. I get approx. 8MB/s in diskperf in DOS with UNDI, approx. 250KB/s with tg3 driver.
