Ok, so you seems to have missed a 'go fast' parameter.
In my opinion, it is not your fault. It is mina that is not being user
friendly. MINA should take care of these details itself.
This optimization wisdom should be capture into mina so that everyone is
not forced to be an expert to have a fast server.
For me, mina should be fast by default (if you want to overwrite the
config you can). Right now mina is slow by default and only if you tweak
some settings it becomes faster. This is not right.

Greg,
I have done some more test, on the 'big server' ( 8 CPUs), changing the
SocketAcceptor initialization with something like what you suggested :
tcpAcceptor = new SocketAcceptor(
Runtime.getRuntime().availableProcessors(),
threadPoolExecutor );
(we already have this threadPoolExecutor, so I reuse it).
The result is huge : I can get as much as 6400 request/s, instead of
only 2000 previously ! And the CPU reach 85% of user+syst usage (70%
user, 10 to 15% system)
This is just what I expected :)
I have more tests to do, but this is a big step in the good direction !
Thanks a lot !
Emmanuel
