We use CeWolf v1.0.0 (with JFreeChart v1.0.0).

A simple test (JSP) page (with 11 pieCharts) show a scalability problem with any stress tool.
(NB : looking at cewolf code, we can see many 'synchronised' ; is it normal ?)

Example of stress test results (with WebLogic) :
- 1 http request : 3,7 sec
- 10 requests/1sec : from 25 sec to 33 sec
- 50 requests/1sec : from 159 sec to 283 sec

Does somebody use CeWolf in real business application ?

Do you know this kind of problems ?

What are your recommandations in such environnement for using several charts in a JSP page ?
