I've just uploaded 0.9.11-pre12 of the GPL PV drivers for Windows.

Since -pre10 (and -pre11) I've fixed a heap of crashes that were
plaguing xennet under load, and also rewritten the interrupt/event
distribution logic to improve performance.

Under windows 2003 I can now get network speeds of 1-2Gbit/second TX and
600Gbit/second RX, which is considerably better than I was getting

Please download it and give it a go.

While these numbers seem to be true for the RX/TX tests between domU <-> dom0, they don't apply to the domU <-> other physical node on lan. The RX is fine, on my 100mbit lan I get about 94 / 95mbit. But the TX is very poor: only 18-20mbit. This has been since all versions I've tested before, but of course hoped this one would make the difference. I've compared the results with a Linux domU PV, which does perform as expected (94-95mbit for both RX/TX).
