Hello

It shows the new feature reusport from v1.9.1 can increase the QPS by 2-3 times than accept_mutex on and off in this article https://www.nginx.com/blog/socket-sharding-nginx-release-1-9-1/. But the result is disappointed when we have the test in our production with V1.11.2.2. It don't even have the improvement but reduced, by 10%, dropped from 42K QPS(with accept_mutex off) to 38K QPS(with reuseport enabled). and it indeed reduce the latency. The two test cases have anything identicial except that the later have reuseport enabled. I wonder if I have missed some special configuration.

Thanks.
