> In our project, we kept all of the source codes of SimpleHostRoutingFilter, used Http11NioProtocol, the codes are following:
> class GkTomcatConnectorCustomizer implements TomcatConnectorCustomizer {
> public void customize(Connector connector) {
> Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
> protocol.setProcessorCache(4000);
> protocol.setMaxConnections(4000);
> protocol.setMaxThreads(5000);
> protocol.setMinSpareThreads(100);
> protocol.setConnectionTimeout(60*1000);
> }
