[struts-menu] Performance problems

Hello All,
Before decided using TabbedMenuDisplayer, I was testing with
VelocityDisplayer.
Now, I am using TabbedMenuDisplayer. 
But I still have /Web-inf/classes/goblaMacros.vm and /templates/tabs.html
in my war file. 
Can anyone tell me why it is starting Velocity now?
Also, how can I set the logging level to WARN for struts-menu classes?

We just ran the stress test on a web app. developed using Struts-Menu 2.0
and Struts 1.1.
Overall, the application appeared to slow down significantly with only "50"
users, the average response time on my PC was about 30 seconds to bring up a
page (this does not include running a query, just clicking on a struts-menu
tab heading). 
Server stats showed disk and memory usage being pretty low on the web
server. There appeared to be hardly any paging or swapping. However, the CPU
was pinned at 98-100% with only a few users. We noticed a constant CPU of
98% with only "10" users. 

We are always thinking about struts-menu code for performance problems.
Is there any document that gives stress test results of a web app. that uses
struts-menu?

Any help is appreciated.
