Powerapps best practices - lenght of form/performance

[Christy_Roach]

I have created a form for my business line that is very lenghthy - something like 70 fields.  We are having performance issues when the users try to access the form - it comes up very slowly and takes some time to come up completely.  We are in SharePoint Online. 

Is there a best practice as to the length the form should be to allow for the best performance?

This is really going to be one of those "depends" answers.

Depends on how you are loading your data and the size of the data.  Are these big SharePoint lists and are you collecting all the records in them?

You mention 70 fields (which is not that bad) - but it depends on how you are connecting them to the datasource and where they are coming from (i.e. a Gallery or is this SharePointIntegrated?)

Are all the 70 fields on one screen or do you have this over several?

Are you using EditForms or are you ding your own layout and controls?

Many factors to this - perhaps evaluation of some of the above can provide some help in your issue.

Hope this helps take you to the next step.

I have a form that is based on a SharePoint online list that has over 80 columns (fields) and over 12,000 records.

I am displaying the fields in a tabbed format based on a form. I am using visible property to show and hide the fields based on selected tab.

For each tab, I display a filtered set of records.

I can't say it is fast but it is usable.

I have noticed that both the number of columns and records have an impact on the perfomance of the app.

The more the number of records, the longer the tab takes to load and render the fields.

For recommendation I would suggest that you try to filter the records and test performance with a smaller number of fields on the screen and see if there is any improvement.

Hi @Christy_Roach ,

Please check below documentation about some tips to improve performance in PowerApps:

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/performance-tips

https://powerapps.microsoft.com/en-us/blog/performance-considerations-with-powerapps/

Personally, I'd suggest that try to first collect the SharePoint list into local collection.
