Im very interested in some performance-tunings tips, too.

We are currently developing a portal application with jboss portal 2.6.5GA and richfaces 3.2.2. The target (client)platform is Windows 2000 (SP4) with IE6 (SP1) and we've got massive performance problems while working with our portal-application in this combination. The IE uses up to 500MB of ram and works realy slowly. We guess a memory-leak in richfaces framework or an error in WindowsScriptingHost. Using Firefox is quite a little bit faster, but far away from a acceptable performance. 
A complete page refresh takes up to 30 seconds, the server cpu-usage never reaches 10 percent while the client-cpu works with 100 percent usage all the time.
With Windows XP the performance is good, could be better, but a page refresh is done in 3-4 seconds. 

We searched alot and didnt found anything helping us. I Just want to know if there are any known Bugs with JBoss Portal, Richfaces & Windows 2000. If someone got a solution for our problem, we would be very thankful :)

kind regards
