to handle many thousands concurrent users, you can even

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
