Hi,
my qemu integrated pvUSB backend is now running stable enough to do
some basic performance measurements. I've passed a memory-stick with
about 90MB of data on it to a pv-domU. Then I read all the data on
it with tar and looked how long this would take (elapsed time):
in dom0: 5.2s
in domU with kernel backend: 6.1s
in domU with qemu backend: 8.2s
So the qemu backend is about 30% slower than the kernel backend. Is
this acceptable?
If I can ask (I know nothing about USB, let alone pvUSB! :-O), and if
you happen to know, what's the situation of other hypervisors, in term
both of support and performance?
No specific knowledge, sorry.
Juergen
