There were architectural changes between 18.104.22.168.500 and 22.214.171.124 that made cube performance change. We had to go back and retune most of our apps. In some cases we had to change Stored and Dynamic dimension settings. Where in the past stored was always better, we found a few cases where a dimension as dynamic was better. You may need to play around with them a bit. Ultimately we got better performance when tuning was complete, but lift and shift was not going to work.
