Microsoft Power BI Performance Best Practices

By: Bhavik Merchant

Overview of this book

This book comprehensively covers every layer of Power BI, from the report canvas to data modeling, transformations, storage, and architecture. Developers and architects working with any area of Power BI will be able to put their knowledge to work with this practical guide to design and implement at every stage of the analytics solution development process. This book is not only a unique collection of best practices and tips, but also provides you with a hands-on approach to identifying and fixing common performance issues. Complete with explanations of essential concepts and practical examples, you’ll learn about common design choices that affect performance and consume more resources and how to avoid these problems. You’ll grasp the general architectural issues and settings that broadly affect most solutions. As you progress, you’ll walk through each layer of a typical Power BI solution, learning how to ensure your designs can handle scale while not sacrificing usability. You’ll focus on the data layer and then work your way up to report design. We will also cover Power BI Premium and load testing. By the end of this Power BI book, you’ll be able to confidently maintain well-performing Power BI solutions with reduced effort and know how to use freely available tools and a systematic process to monitor and diagnose performance problems.

Chapter 5: Desktop Performance Analyzer

In the previous chapter, we looked at ways to get performance and usage information from the Power BI service through reports and logs. This is real-world data that's provided by Microsoft through various features, though there are currently some limitations as to what questions it can answer. For Power BI reports, we often need to know whether visuals, queries, or combinations thereof are slow. Some of this granularity isn't available from the Power BI service in production at the time of writing. However, you can get much more granular performance information in Power BI Desktop through the built-in Performance Analyzer.

As we progress through this book, you will learn how the end user report performance experience can be affected by many different factors. A good way to pinpoint these is to analyze report behavior at the level of each user interaction, and the behavior of each visual in response to that action.
