I have 2 CMS servers and 8 WEBI report servers on windows. Most reports are run-time query execution. When there are a lot of concurrent users, I notice the memory footprint is very uneven. One webi server is at 1.4G (max) while some other ones are barely at 300M. Does CMS do round-robin load balancing among webi report servers? How does CMS decides which webi report server to use? Thanks.
