A Power BI analyst significantly reduced report load times from 14 seconds to under 2 seconds by optimizing the data model, rather than relying on hardware upgrades. The key to this improvement was restructuring the data from a single, large flat table into a star schema, which is more efficient for Power BI's VertiPaq storage engine. The analyst used tools like Performance Analyzer, DAX Studio, and VertiPaq Analyzer to identify bottlenecks, finding that most of the delay was due to inefficient data retrieval (DAX query) rather than visual rendering.
