Hi Artec. Some items I would start with; 1) Make sure enough DB connections in the JBoss Container for the number of worker threads that the JBoss & the WebServer are using. In other words, if setting minimum & maximum on the WebServer, your min. & max db connections should be the relative to the WebServer's. And by relative, I mean approx. what percentage of Web hits == DB Hits. 2) Database side - make sure that its Connection parameters are set to handle the maximum number of connections from all JBoss instances. 3) Check out Jetty (http://mortbay.org) for your Servlet & JSP container. Its FAST! 4) Higher number of threads DOES NOT NECESSARILY EQUAL better throughput. That is also a function of number of CPU's. Look at setting worker threads (but that's another topic). Grinder tends to make a decent tool for finding performance bottlenecks. http://grinder.sourceforge.net/ TEST TEST TEST TEST!
