performance of Profound UI on webserver

I would appreciate any feedback on system performance in a production environment utilizing Profound Logic's UI product (w/RPG handler) as well
as the Genie product (run your greenscreen in a browser). Did you have to upgrade your server to implement? Since this is a vendor product, offline may be preferred. We know there is overhead, it's a difficult test to eval with 100+ very active users..
