  • GraniteDS & Asynchronous Servlets
  • to handle many thousands concurrent users, you can even
  • create a cluster of GraniteDS servers
  • ...9 more annotations...
  • Asynchronous Servlets Performance
  • With a non NIO or non Continuation based server, this would require around 11,000 threads to handle 10,000 simultaneous users. Jetty handles this number of connections with only 250 threads.
  • Classical synchronous model: 10,000 concurrent users -> 11,000 server threads. 1.1 ratio.
  • Comet asynchronous model: 10,000 concurrent users -> 250 server threads. 0.025 ratio.
  • classical (synchronous) servlet model
  • request -> immediate processing -> response
  • Comet implementations rely on a different model:
  • request -> wait for available data -> response
  • With synchronous servlet processing, each request is handled by one dedicated server thread
