Overhead of remoting filters

[timfox]

I'd be interesting in knowing what's the overhead of the keep alive and the request-response filters on non request-response traffic.

A simple test would be very useful - send some decoupled non request-response traffic both with and without these filters enabled and measure the difference.

I've used MinaSessionTest.testWriteMany() and sent 50K messages to get some figures on these filters.
There is some variation on these figures so they're to be taken with a grain of salt:

with reqres & keepalive filters
===============================
duration: 6242 ms

without reqres filter
=====================
duration: 6057 ms
=> duration decreases by 3%

without keepalive filter
========================
duration: 5802 ms
=> duration decreases by 7%

without reqres & keepalive filters
==================================
duration: 5507 ms
=> duration decreases by 11%
