public int getMinThreadCount() {

Returns the min number of threads the channel will use for processing messages.
The channel will automatically de-allocate worker threads as the queue load shrinks,
down to the defined minimum. This lets the channel consume fewer resources when load
is low.

@return the min number of threads that can be used by the channel.
