Is "WRITE:" logged?  If so, how long is the interval between your write()
call and "WRITE:" message?

If you can reproduce this issue easily, please let me try it by myself.

I try to modify the ThreadPool's size to 10-1000 ,but the performance

IoSession.write() method and the number of thread pool don't have any
relationship.  If it is slow like that, it might be the problem of the
implementation or MINA.

Hi Trustin:
I have monitored my server by JProfiler today,and find the performance
problem coming from log4j and Java Service Wrapper's log.
Sorry,it's my mistake.

Best regards!
