🚀 Boosting Power BI Performance with DAX Optimization! 🚀 As a Power BI user, I recently tackled a challenging project: optimizing a complex Power BI report brimming with DAX measures. The initial performance was far from ideal, but with determination and the right tools, I managed to significantly improve the refresh speed. Here’s a glimpse into my process: 1️⃣ Performance Analysis: I utilized Power BI’s Performance Analyzer function to identify bottlenecks in the report. 2️⃣ In-Depth Query Inspection: By leveraging DAX Studio’s Query Plan and Server Timings functions, I was able to run and scrutinize each DAX measure individually. 3️⃣ Step-by-Step Optimization: Focusing on one measure at a time, I meticulously optimized the DAX queries, enhancing their efficiency and reducing execution time. The result? A much faster and more responsive Power BI report that delivers insights more swiftly and effectively. 💡 If you’re looking to enhance your Power BI reports, I highly recommend diving into these powerful tools. The effort is well worth it when you see the performance improvements! Below is a great video for you to get familiar with these tools. https://lnkd.in/g3MB8jsQ
