This is a UDP test. So the sender will not wait for receiver. In the
result, you can find that the sender throughput reduces 60.4%, while the
receiver throughput increases 249.7%. And, much less packets are
dropped during the test, and this is good too.
All in all, considering the performance of both the sender and the
receiver, I think the patch helps the performance.
