Why are performance issues seen with SSO-enabled environments?

Why am I seeing performance issues with IBM TRIRIGA while using the WebSphere IHS SSO-enabled environment, but not when directly accessing the server (not SSO-enabled)? Users have been reporting poor performance when connecting to IBM TRIRIGA via the SSO-enabled environment. If users connect to the same environment, but using a non-SSO-enabled server/JVM, the performance is acceptable. Why is this happening?

This turns out to be a WebSphere IHS SSO configuration issue… Comparing direct to application server versus via IHS/PLG proxy is like trying to compare apples and oranges. When via IHS/PLG, there are additional headers involved and load balancing. Direct only goes to one cluster member…

This case is out of the scope of IBM TRIRIGA Support, since we cannot troubleshoot application server and web server SSO configuration… You will need to engage the IBM WebSphere IHS (IBM HTTP Server) Support team on this case, by creating a PMR for them to work with this issue. Make sure you classify the PMR as being a WebSphere product PMR, and make sure to note in the PMR description that this is an assistance request for the WebSphere IHS team.
