cometd: 基于jetty 的压力测试步骤

http://docs.codehaus.org/display/JETTY/Stress+Testing+Cometd

 

 

Jetty comes with cometd installed in $JETTY_HOME/webapps/cometd.war.
To run the server with additional memory needed for the test, use:

java -Xmx2048m -jar start.jar etc/jetty.xml

While the test is executing, a series of digits is output to show progress. The digits represent the current average latency in units of 100ms. So a 0 represent <100ms latency from the time the message was publish by the client to when it has been received on the client. 1 represents a latency >=100ms and <200ms etc.

Also a real chat room server implementation would probably be backed by JMS so that multiple nodes would still represent a single chat space.(意味着可以利用JMS来做集群？)
