> ListenTCP processor and other processors in the listen family are reserve resources at initialisation based on properties on the processor. This includes:
>  * Executor in SocketChannelDispatcher is created using fixed thread pool
>  * Byte buffer pool is build up based on Max Number of TCP Connections which with high connection can consume high amount of memory
> In some use cases this is undesirable and might even cause failure of the initialisation. In order to avoid this I suggest to remove the buffer pool and replace the fixed thread pool into a more flexible (scaling) implementation.
