Troubleshoot Power Apps canvas app performance issues
Tip
For performance issues, you can use profiling tools like Monitor and Performance insights to debug and diagnose problems.
The following table outlines common performance issues you might encounter while using a canvas app, along with likely causes and recommendations. High-level issues are linked to more detailed documentation through their associated causes and recommendations. Some recommendations might appear multiple times, as the root cause can manifest in various symptoms.
| Problem/Symptom | Likely cause | Recommendations |
|---|---|---|
| Slow app/page load times | - Overloaded OnStart - Large data sets - Many cross-screen references - Heavy media files |
- Move calculations out of OnStart - Use small data payloads - Defer loading data - Optimize resource usage – media, controls, references |
| Large data payloads | - Retrieving unnecessary data - Large data sets |
- Use small data payloads - Use delegation - Prefilter data at the source - Limit data retrieval |
| Inefficient data queries | - Nondelegable queries - Complex data operations |
- Use delegation - Optimize query patterns |
| Inefficient calculations | - Complex formulas - Repeated calculations |
- Optimize formulas - Split up long formulas |
| Overall slow app performance | - Inefficient data retrieval - Many cross-screen references - Complex formulas - Overly large apps |
- Optimize data sources - Optimize formulas - Use collections for small, frequently used data - Split up apps |
