To what the author has said, I will add that in terms of performance, Netty is currently faster than the fastest production Servlet containers [1]. Presently, Undertow (the web server for the upcoming WildFly application server, which will have a Servlet container) is the only platform providing slightly faster request-processing performance. Until WildFly is production-ready, Resin is the highest-performance Servlet container I am aware of.
