My server is designed for web page-view statistic, so it must support

Did I do anything wrong?? or is it a problem of mina? I need your help...
Alas, MINA does not perform the best when you do frequent setup/teardown
of connections, due to the latency it involves on the MINA side in the
context switch between the acceptor thread and the processing threads.
We'd like to address this for 2.0, but don't have any code written on it
yet. If you want to help, that'd be great! :)
I have a related problem. We have just started load testing one of our
simple servers. Nothing fancy, no tuning done as of yet, using MINA 1.1.0.
When our load testing script generates incoming connections rapidly, our
server starts refusing connections after 400 connections. When it's done
at a slower pace we start to get refused connections after 800
established ones. I have one suspicion, but I'd like to confirm if
someone can tell me directly what's causing this behaviour?
