Tuning IG's Tomcat Container
Configure the Tomcat container in conjunction with IG, as described in "Tuning the ClientHandler/ReverseProxyHandler".
To take advantage of IG's asynchronous thread model, configure Tomcat to use a non-blocking, NIO or NIO2 connector. Consider configuring the following connector attributes:
maxConnections
connectionTimeout
soTimeout
acceptCount
executor
maxThreads
minSpareThreads
