Re: [Xen-users] Release 0.8.0 of GPL PV Drivers for Windows

Hi Jim,

I see ioemu in the vif= line in your config file. did you try using netfront instead (possibly with a different MAC ID)?

This performance is extremely bad if it's around 1,4 Mbytes/sec. I'll try to test tonight on my own system.

Thanks,

Emre

I wish. Maybe when I upgrade to a 64 bit system, domu to dom0 communication
will be faster. I suppose at least that is independent of the physical nic
(which is just 100Mbps), being a software only (apparently ipv6) nic.

From the previously mentioned benchmark results post:

Equipment: core duo 2300, 1.66ghz each, sata drive configured for UDMA/100
System: fc8 32bit pae, xen 3.1.2, xen.gz 3.1.0-rc7, dom0 2.6.21
Tested hvm: XP Pro SP2, 2002, tested w/ iometer [...]

I checked everything it would let me, including acpi & smp:
