   > NettyServer -> new DefaultEventLoopGroup (16);
   > I am not sure whether the number of threads 16 meets the needs of the job.
   > In practice and application, regardless of memory consumption, I like to use the thread number formula to calculate
   > Nthreads = Ncpu * Ucpu * (1 + w / c);
   > So I think 16 can be used as the default value and the settings can be passed in through the constructor.
   
   I updated NettyServer to allow passing EventLoopGroup objects for each of the three groups it uses.   Thus, the user could configure each of the three as needed.
