What are the performance issues resolved in Power apps

Performance issues in the Power Platform can arise from poorly optimized apps, flows, or data sources. Here’s a list of common performance issues and how they are resolved across Power Apps, Power Automate, and Power BI.

🔧 Common Performance Issues & Resolutions
1. 

Slow App Load Times (Power Apps)

Issue: App takes too long to load due to too many controls, screens, or unoptimized queries.

Resolution:

1. Use delegation-friendly queries (especially with large data sources).
2. Reduce screen controls and use components or collections.
3. Load data on demand instead of on app start.
4. Avoid unnecessary use of Set() and ClearCollect() on app startup.
   

2. 

Unresponsive Workflows (Power Automate)

Issue: Flows are delayed, stuck, or fail due to API timeouts or poor branching.

Resolution:

1. Add “Configure Run After” and timeout handling.
2. Use parallel branches where possible.
3. Optimize condition blocks and avoid redundant loops.
4. Avoid calling premium connectors unnecessarily.
   

3. 

Poor Power BI Report Performance

Issue: Reports take long to load, refresh, or render visualizations.

Resolution:

1. Reduce visuals per page and avoid complex measures.
2. Use Import mode instead of DirectQuery when possible.
3. Optimize DAX expressions.
4. Implement data aggregation and use Power Query transformations efficiently.

4. 

Dataverse Query Slowness

Issue: Queries to Dataverse are slow or time out.

Resolution:

1. Use indexed columns in views and filters.
2. Limit the number of related tables queried.
3. Avoid pulling all columns (select only necessary ones).
4. Cache data using collections or variables.
   

5. 

Mobile App Lag (Power Apps mobile)

Issue: App runs slow or crashes on mobile.

Resolution:

1. Optimize image sizes and remove unused media.
2. Use device-specific logic to disable heavy features on mobile.
3. Minimize concurrent calls to data sources.
   

6. 

Environment Performance Degradation

Issue: Multiple apps and flows across environments slow down overall system.

Resolution:

1. Use separate environments for Dev/Test/Prod.
2. Monitor app performance via Power Platform Admin Center.
3. Remove unused or orphaned apps/flows.

7. 

Inefficient Expressions and Formulas (Canvas Apps)

Issue: Use of nested If(), Switch(), or repeated LookUp() causes delays.

Resolution:

1. Replace If() chains with Switch().
2. Use With() for readability and reusability.
3. Use ForAll() with inline logic instead of calling Patch() multiple times.
