Hmm there aren't a lot of numbers there :(. Speed increased by 33% but
by how much? E.g. maybe you are getting from 1Mbyte/sec to 1.3,
if so it's hard to get excited about it. Some questions that come to
mind: what was the message size? I would expect several measurements
with different values. How did host CPU utilization change?
What about latency? As we are competing with guest for host CPU,
would worst-case or average latency suffer?
Thanks,
