Identify performance considerations for a mobile-optimized canvas app

Power Apps provides built-in tools that help make it easier to identify performance issues. This video introduces the App checker, a valuable tool for diagnosing app problems.

In addition to using the App checker, more advanced users can use Power Apps Monitor to identify potential performance bottlenecks. However, App checker is the most accessible performance troubleshooting feature.

To improve performance, reduce the amount of data your app needs to access. Apps that retrieve less data generally perform better. Also, minimizing the number of "gates" or connectors that data must pass through can enhance speed.

Among the data sources available, Dataverse typically offers the best performance. Because Microsoft Power Apps and Dataverse exist within the same environment, data access doesn't require API calls.

Other sources may introduce latency. For example, data from an on-premises server must go through an on-premises data gateway. Although cloud-based SQL databases are strong options, they still rely on API calls. SharePoint can be effective for smaller data loads but may slow down as list size increases due to API dependencies.

To optimize performance:

• Limit the amount of data the app retrieves.

• Design galleries and forms to source data from a single data source when possible.

Performance is especially critical in mobile scenarios. As your app scales, continue to prioritize efficient data access and responsiveness.
