Thanks Michael for the info. J2EE performance testing depends on many different factors. Some questions/suggestions for your consideration:
1. It wasn't clear from your report what the HW/SW spec of your test clients (load workstation). Base on your test scenario, it looks like each load workstation would have to generate 200 - 400 user sessions. If you were using 512 MB RAM in your client as the server, it may not be sufficient enough to handle the load. 2. What was the ramp-up rate? i.e. the number of users added per second? 3. How were the timeout parameter configured in your tomcat server and client? I think many of the errors were caused due to server timeout. 4. What was the threading configuration on tomcat? If you have a Pentium with HT, you can use a large number for configuring tomcat's thread pool. Thanks!

The articles are available here: http://webperformance.com/library/reports It describes the very different behavior of the two platforms under load, and shows there is a significant different in performance. Under the restricted conditions of the test Linux was able to handle 32% more load than Windows with identical versions of Tomcat on identical hardware.
