Where can I find the client side code for this test? I think I found it once 
before and discovered the way the response times were calculated were incorrect.
What I saw indicated your test results were divideing the number of requests 
into the time it took for all of them to complete when the tests were run in 
parallel so it made it look like the requests were faster than they really were. 
It was like taking ten 100ms requests run in parallel and getting 10ms per 
request when in reality it was 100ms.

In either case I will see what if I can find again the client side code 
soemwhere and compare it to what I have unless you have a link to it.

HttpClient 4.1 is known to be comfortably faster than 3.1. There is
likely to be a problem with how you are measuring performance / response
