While this isn't wonderful, it's not your major bottleneck now. What's
the bandwidth generated by the workload?

Now this is bad. Please provide the output of 'kvm_stat -1' while this
is running. Also, describe the guest. Is it Linux? if so, i386 or
x86_64? and is CONFIG_HIGHMEM enabled?
UDP performance is a known issue now, and we are working on it. TCP is
much better due to segmentation offload.
