There are load test results, for struts1, up to 200 concurrent users with 0.75 sec timeout, result: 2% timeout for struts2, up to 10 concurrent users with 5 sec timeout, result: 80% timeout
------------------------>>> the application is the same, for struts2 ognl language is used, but is optimized (ognl is replaced with simple struts/jsp tags where possible) I think this is enough to consider struts2 slow. Best, Aram
