We are working on improving SPDY's performance, and although the work is mostly geared towards server performance, the client will benefit too (it's the same codebase). HttpClient's HTTP transport has been really fine tuned for performance because we use it as our primary load test tool. I'm interested in following up on this. I will be out the first half of the week to a conference, but meanwhile you have your test code available ? We did measure SPDY to be vastly better than HTTP when used in conjunction with browsers, which only allocates 6 HTTP connections. Measurements with a Java client may really be different depending on the client configuration and so forth, so a detailed description of your tests and the code are really important to clearly understand your use case. For example, I would expect performance to vary if the client is tuned for large uploads or for small downloads, etc. I'll try to follow up on this thread; meanwhile, please file an issue about this, so we won't forget.
