I am seeing nothing that might suggest an obvious performance related problem.

I am fairly confident about this number. If you are not registering any performance improvement this basically tell me that one of two things are likely to be true (1) the overhead of HTTP protocol processing is negligible compared to the time spent transmitting and processing message content. (2) the problem is on the server side. Response latency is much greater than the overhead of HTTP protocol processing. The client side HTTP does not appears to be the performance hot spot. I _suspect_ you are optimizing the wrong component.
