Power Apps Performance in 2026: 10 Fixes That Actually Move the Needle

-

If your Canvas app feels slow, users will not care how elegant your formulas are—they will just stop using it.

The good news: most Power Apps performance issues come from a small set of patterns that are easy to fix once you know where to look.

In this guide, I will walk through 10 practical optimizations you can apply immediately.

1. Start with Monitor before changing formulas

Open Monitor and reproduce the slow action. Look for long connector calls, repeated queries, large payloads, and screen navigation delays. If you do not measure first, you will optimize the wrong thing.

2. Reduce chatty data calls

A common anti-pattern is querying the same data source multiple times in one screen load. Use With() or Set() to capture results once and reuse them in controls.

3. Filter at the source (delegation-first)

Keep filters delegable so your data source does the heavy lifting. Non-delegable formulas force client-side processing and can silently truncate results.

4. Load only what users need now

Avoid loading everything on App.OnStart. Use a staged approach:

  • Load essentials for the first screen
  • Lazy-load secondary data after the screen renders
  • Preload next-screen data only when needed

5. Avoid expensive controls in big galleries

Nested galleries, heavy templates, and many dynamic labels can slow rendering. Simplify templates and reduce per-row formula complexity.

6. Use named formulas for reusable logic

If the same computation appears across multiple controls, centralize it with named formulas. You improve maintainability and reduce repeated recalculation.

7. Batch writes whenever possible

For bulk updates, avoid one-row-at-a-time patterns. Use table-based operations and reduce round trips to Dataverse or SharePoint.

8. Keep media assets optimized

Large uncompressed images or background media can delay app startup. Compress assets and use appropriate dimensions for target devices.

9. Separate admin and user experiences

If one app does everything (admin, analytics, operations), performance often suffers. Split by persona or role when complexity grows.

10. Re-test after every optimization

Performance gains are cumulative but easy to misread. Re-check with Monitor after each change and keep a short change log of what improved.

Quick performance checklist

  • Delegation warnings resolved
  • No redundant connector calls
  • First screen usable in under 2–3 seconds
  • Gallery templates simplified
  • Data loading staged by user journey
  • Monitor traces saved for before/after comparison

Final thought

Power Apps performance is less about one magic formula and more about disciplined architecture. If you optimize data access, rendering, and app startup together, users will notice the difference immediately.

Power Automate Pagination: How to Retrieve More Than 5000 Items from a SharePoint List

-
One of the common scenarios that you may encounter when using Power Automate is to retrieve data from a SharePoint list and perform some actions on it. However, if your SharePoint list has more than 5000 items, you may run into some challenges and limitations. In this blog, we will explain why this happens and how to overcome it using pagination. Why does Power Automate have a limit of 5000 items for SharePoint lists? The reason why Power Automate has a limit of 5000 items for SharePoint lists is because of the underlying SharePoint API that Power Automate uses to connect to SharePoint. SharePoint has a feature called list view threshold, which limits the number of items that can be returned in a single query to 5000 by default. This is to prevent performance issues and ensure optimal performance for all users. If you try to query more than 5000 items from a SharePoint list, you will get an error message like this: This error message will also appear in Power Automate if you use the Ge...
