Yes, I don't intend to create one thread per connection in asynchronous
case. Just for this sample use case I created a thread on connection request
and used it to generate messages. My main concern is, if we are trying to
send messages asynchronously (in non-ioservice thread) then the performance
is significantly bad compare to sending the messages synchronously in the
connection thread (of course if more and more number of clients get added
then thread-per-connection in synchronous case won't scale well).
