The concurrency Protocol of the Tomcat Protocol Http11nioprotocol

The rationale for this protocol is unclear, but the protocol (HTTP11NIOPROTOCOL) can improve the performance of Tomcat when high concurrency is pending.

The default is http/1.1, which is the blocking type, After switching to Org.apache.coyote.http11.Http11NioProtocol, the request is processed in a non-blocking manner, which allows for a certain amount of concurrency, although, in later versions of tomcat7.0, even http/1.1, However, instead of the original blocking protocol, the ORG.APACHE.COYOTE.HTTP11.HTTPAPRPROTOCOL protocol is used (ensuring that the Tcnative-1.dll file exists in the Bin directory and configured in the Server.xml < Listener classname= "Org.apache.catalina.core.AprLifecycleListener" sslengine= "on"/> so that, without changing the protocol, Using the Httpaprprotocol protocol, however, the sub-protocol is still blocked, but the use of dynamic link library, so that performance than the original http/1.1 have a certain increase, see the official documents (the following official comparison):

The specific performance is also tested in a real-world environment, and the same set of configurations is not the same in different environments.
