Libwww goes through a lot of efforts to cut down on the number of TCP connections and really only allows a single TCP connection at a time to a specific host, port. When I want to stress test a server, I start multiple libwww robots and point them at the same site - this puts a lot of load on the server and can show how the server handles pipelined requests and not only how fast it can swap contexts. The HTTP/1.0 mode doesn't force multiple connections to open, it still uses a single connection at a time.
