3275307 - Peformance problems after the upgrade QRC4 upgrade

After the Q4.2022 upgrade we noticed some performance problems. Story refresh takes up to 15 times longer than usual.

The issue affected only the stories based on the classic model type.

The new model types are not affected. 

SAP Analytics Cloud version: 2022.21.7 

1. Login to tenant: 

2. Refresh story

3. Observe it takes more than two minutes to refresh (about 155 seconds). Before the update it was around 10 seconds on the same story

4. The Performance analysis tool shows the delay on the backend, not the front end.

The problem is intermittent
