You have an application problem, not a problem with Tomcat. I hit 23 requests per second on a uni-processor P4 3.0. Incidentally, if you look at my results you'll see that the average time for pages involving DB Access is 350ms, while the average time for pages not involving DB Access is 81ms. Here are some performance testing numbers for my app. http://www.mhsoftware.com/caldemo/manual/en/pageFinder.html?page=622.htm Note that my app is handcoded servlets, and doesn't involve JSP or tag libraries. You might want to upgrade to the latest JDKs. In my testing, going to the JDK 1.5 yielded something like a 25% increase in performance.
