A number of nodes and machines and networks are involved in your test so you need to somehow further isolate the problem. In place of the go http server, you can just put a simple C/C++ based listener that accepts connections and closes them right away -- that should measure raw connection accept rate. You can try running an equivalent server in some other language. Could the issue be with the machine running the test programm itself? You can try running the test with the http server running on *another* machine.
