In this case, NIO is a lot faster. Turn off keepalive on ab, and we get similar results to previous run, where BIO is a tad faster. Scaling the thread per connection model is done by increasing the amount of threads. This particular test demonstrates the obvious. yes, what is interesting though, is my NIO connector is not really true NIO, as it ties up a thread while polling for data. The true implementation would have not invoked that thread yet, but for that I would have had to rewritten the connector from scratch as I couldn't have taken advantage of code already written and tested. The reason it was done like this, is cause that way I could use almost all the code from the APR connector. So you could call it a semi-"thread-per-connection" model, yet handles better than the true thread per connection model. APR does the same thing. If I understand the results correctly, the results would be acceptable on Unix. yes, I think they are looking pretty good. And I am fairly confident in this new code, as most of it, is old tested APR code. Filip -- Filip Hanik
