Having read that, my primary conclusion is that the tested 
implementations were making such poor use of HTTP/1.1 that
any attempt to pull out other issues is futile.  None were 
using chunked encoding for either requests or responses, 
which means that the entire message must be marshalled before
any part can be sent, and none were disabling the Nagle
algorithm for the TCP connection.  

There are several good papers available on this at 
    http://www.w3.org/WCA/
