Zulfi, I attached the full source code of the tests. Please once again see the link http://marc.theaimsgroup.com/?l=httpclient-commons-dev&m=109300858528261&w=2 Feel free to do more research in that area and post us on the results. I just know for a fact that due to the design limitations HttpURLConnection always buffers the request body, so HttpClient is bound to be faster (especially when executing POST requests in multiple threads) for any but the tiniest requests when configured to stream out the request body.
