Hi All,

I Have a Canvas PowerApps in that

First Page :

I have a Gallery with contains 10 Fields ( All fields with Sorting)

So for that we created Button for Each 10 Fields based on the Sorting am setting a TEMP VARIABLE VALUES based on that the respective Button with Call and filter the Grid.

When the Record count was with in 2000 it worked very fast but after that it became too slow.

For Eg

in the First Page i have a Button to Create a new Record. If i Click on that it will Open a Form and i will fill all the details and Save it will save to back End.

once saved it will renavigate to gallery and again it is making QUERY to database and filtering and showing it in GRID. Any way we can optimize this more than 2k records.

Canvas PowerApps Slowness

Hi @Ram Prakash , To optimize Canvas Power Apps performance with more than 2,000 records, use delegation, cache data in collections, and minimize re-querying the data source after each action.

Optimization Topics

• Use Delegation-Friendly Queries
• Cache Data in Collections
• Avoid Re-querying After Save
• Use Concurrent Loading
• Reduce Control Count and Complexity
• Enable DelayOutput on Text Inputs
• Consider Elastic Tables for Scaling

• Microsoft Learn – Optimize performance for bulk operations

Hi @Ram Prakash,

What we relly need to know here is some formulas, particularly the Items of that Gallery and what you are doing on those buttons (what are those Variables you are referring to and how are you using them). I assume you are using SharePoint here as the data source.
