Slow rendering portal pages?
If you are having trouble getting your portal pages to render in a decent amount of time here is a little trick that can greatly improve performance.
When rendering a report in Cognos viewer portlet, in a portal page, the hour glass may just spin and spin. If the report runs fine on its own and is only slow in a portal page, then try this: instead of using a Cognos viewer portlet to render the report, use an HTML viewer portlet instead. I have used this technique for a dramatic increase in performance with multiple clients.
Stay tuned for more “tricks of the day” blog posts through out the next couple of months!
