@abners Yes you are right, may be we need to clarify in the documentation that no more than 1 selector thread is used when there is a custom configuration.
Take a look here https://stackoverflow.com/questions/28665906/netty-boss-event-loop-and-executor, although the question is not about this, the answer explains very well the boss and worker EventLoopGroup.
Also this one https://stackoverflow.com/questions/28331809/netty-bootstrap-with-boss-group-or-with-just-with-workers-eventloopgroup explains when you may need boss EventLoopGroup.
