Extremly slow performance / PA studio UI unacceptably slow using Gallery control with many records

Hi Everyone!

I am very impressed what is possible with powerapps already. I am trying to "develop" are more complex team planing app where the manager is able to plan working hours of team members (up to 10) working in a bookshop. The manager should be able to simply click on a character and the corresponding hours (e.g. clicking on G equals 8 hours or V equals 4,5 hrs).

The UI of the app is made up like a calendar (calendar days on the x-axis, team members on the y-axis). Using a Gallery a total of 140 records/tiles are shown. In each "tile" of the Gallery I added 9 textboxes. Simply doing that (adding no logic or anythink else) slows down the UI in PA Studio to an extand that you have to wait for 5 seconds until e.g. a selection of a textbox or changing of an attribute is executed. Also, the performance of the app itself is slow two. PA Studio is up-to-date and even on a Surface Book with 16 GB and Intel i7 performance is not improving.

First I had the Gallery bound to a SharePoint List, which made things worse. I am now using a collection to cache the SharePoint List locally. Performance of PA Studio UI and app is totally unacceptable. Please help 🙂

Here a screenshot:

Thanks, Mario

Hi @MarioKitz,

Please take a look into the following thread and see if it would help:

Performance questions for moderately complex app

Please follow what Mr.dang suggested and see if there are any improvements could be made with your app.

The performance is so embarassingly slow that it's becoming impossible to do even simple updates. Clicking items is delayed, moving anything is delayed, even just typing text is slow enough you wonder if your machine is failing... This happens in either the local app editing or the web, both have their own sets of issues.

I've got a Core i7 and 32GB ram with a fast SSD and this program is absolutely horrible on it, I've never ever encountered something that runs this poorly on newer hardware.

I've learned to browse the forum here while waiting on things to happen but my frustration with how poor this runs is through the roof!
