In Information Delivery Portal on 9.4 M3 URL Display Portlets are taking a while to load. This started happening last week and seems to have gradually gotten worse. Stored process portlets display correctly. Home tabs without portlets load fine. Standard Reports run fine. I don't know of a change to the server.
Check out peformance of your SAS mid-tier server. Look at CPU usage and memory. Check server event logs and SAS server logs to see if there are errors happening that might impact performance. We've had problems like this when SAS Environment Manager processes go pear-shaped and start writing zillions of errors to log files.
We ended up changing our middleware IP address and the slowness stopped. Problem solved.
