Question regarding Mina changes

[Michael Bauroth]

Hi,

I was very busy for the last few months so that I had not the chance to 
read much about the Mina progress in this time.
Today I've checked out the latest version and compared it's performance 
against 0.9.5. It seems that it consumes less cpu power but more memory. 
Is this correct so?

Two questions about the changes: Is now per default the Executor 
Threadpool enabled in the acceptor? And the second question: Could there 
be a reason, that establishing of 20000 concurrent connections now needs 
400 seconds against 100 seconds before?

Best Regards
Michael
