Always keep an async_receive() pending at all times and supply a 
thread pool of executors for asio to issue callbacks onto. You can 
easily peg a 1Gbit ethernet connection with a low CPU usage with that 
alone.

If you need to max out a 10Gbit or 40Gbit ethernet connection, come 
back to us. Those have non-trivial design requirements.
