If you look at my posts in the last months, I've conducted a test for network and disk drivers on a Linux HVM running with unmodified_drivers (PV Drivers for Linux).

The result was that Linux HVM with PV drivers performed nearly at the same speed as the Dom0. thus we can say that Windows PV drivers have still some gap to close, but let's try to do a new test with James' latest drivers.

Does anyone have performance numbers for Windows running on these drivers?

An objective and meaningful (hardware independent, more or less) comparison would be Linux PV guest vs Windows with PV drivers; both network and hard disk throughput.
