Does your Power BI matrix take forever to load or throw "Out of Memory" errors? You might be using the wrong tool for the job.

In this video, we run a brutal stress test comparing the traditional Disconnected Table / Field Parameters method against Calculation Groups. The results will shock you—saving up to 11 seconds of load time! BUT... there is a massive plot twist at the end. Calculation Groups aren't always the right answer.
