Hi all,

after several tests it seems that the interrupt assignment on the host
systems influences the kvm performance drastically. If eth0, video and usb
are on seperate interrupts the perfomance is way better than if they are
shared (that means on the same one).

Normally this should not matter. But why is it within kvm? Does kvm somehow
hook up into the interrupt service routines?
My guest is Windows XP SP3.

Best regards,

Erik
