Each new connection to listener socket spawns a new connection. This allows for an arbitrary number of concurrent connections. This has advantages if the workers require a long execution time.</div></li><li><div><b>Fixed pool of workers</b></div><div>This model is selected by passing the number of worker processes to <tt>init/listener</tt> with the keyword <tt>number-fixed-workers</tt>. This model has a lower overhead since new processes are not created and destroyed with each connection. It has advantages when the workers have a short execution time.</div></li></ul><h2>Usage</h2><p>The demo.lisp file for examples of using cl-modlisp.</p></body></html>
