The link Martin posted has no relation to the WebSocket implementation in Tomcat 7. If you build on top of Comet each WebSocket connection automatically gets a lot of unwanted baggage (requests/responses) that potentially hampers scalability. The Tomcat 7 implementation is built on top of Tomcat's low-level I/O and is relatively baggage free. In Tomcat 8 it is built on top of the Servlet 3.1 HTTP Upgrade but the Servlet[Input|Output]Stream objects used are not the same ones you'd get if you requested them from an HttpServlet[Request|Response]. Again, for scalability, the Servlet[Input|Output]Stream implementations used by HTTP upgrade are built on top of Tomcat's low-level I/O.
