We’re excited to reveal the third and final training day for Power BI Next Step 2026 – and it’s a perfect fit for our Next Step audience.
This full-day workshop will be delivered by Darren Gosbell and Greg Baldini.
If you’ve ever experienced Power BI reports that are fast during development but slow once deployed to Premium or Fabric capacity, you already know that performance problems usually come back to one thing: the semantic model.
Fixing these issues requires visibility into what’s actually happening inside the engine. And that’s exactly what this training is about.
During the day you’ll learn how to use DAX Studio to analyze queries, understand VertiPaq storage behavior, and diagnose performance bottlenecks. Through a series of hands-on labs, Darren and Greg will guide you through real-world scenarios where you will:
- Analyze slow visuals and queries
- Understand VertiPaq storage and execution metrics
- Identify common DAX performance anti-patterns
- Apply practical optimizations that improve responsiveness and scalability
By the end of the workshop, you’ll have a much deeper understanding of how Power BI executes your models and how to use DAX Studio as part of your everyday performance tuning toolkit.
And the instructors could hardly be better.
Darren Gosbell, from Microsoft’s Fabric CAT team, is the original author of DAX Studio and a long-time leader in the Analysis Services and Power BI community.
Joining him is Greg Baldini, who many of you know for his deep expertise in building and optimizing high-performance semantic models.
Together they bring both deep engine knowledge and practical optimization experience.
