     cbThreads        The maximum number of threads to be used for callbacks and
                      sets the maximum number of active callbacks (default 300).

     netThreads       The maximum number of threads to be used to handle network
                      traffic. The minimum is 3, the default is 10% of cbThreads
                      but no more than 100.
