Slow performance in Power Apps Studio when building large apps


... so please add a comment, if you face a similar issue.


Let's rally and make some noise!




When building large apps, Power Apps Studio (i.e. the editor) becomes insanely sluggish when the number of screens/controls increases. 


I am currently building an canvas application with more than 100 screens, which works perfect in player-mode - but my ability to proceed with the development is heavily impeded poor performance in the editor (Power Apps Studio).



  • Loading the app in the editor takes 15-20 minutes (and is interrupted by an authentication prompt).
  • When an object is selected, it takes 4-5 seconds before the formula bar is adjusted to the correct code.
  • When a formula is entered, at it takes 10-30 seconds before an intellisense-suggestion appears.
  • Inserting object takes 5-10 seconds (a loading screen appears).
  • Opening "Preview mode" takes 2-5 minutes.



To any Microsoft support staff reading this - you have a problem, which cuts off developers ability to build some serious apps, that actually can be used for more than just handle a simple process. Please fix this.


Many before me have raised this issue - here's 15 examples from a "Power Apps Studio Slow"-google search, where I only looked at the first 3 pages:



I have even raised a ticket to your support staff... to which the response was - "Try to delete some of your screens".

... c'mon - get in the game, please!

Encountering the same issue on a 3-screen app with one of those screens with 650 controls. It really isn't that complicated. It's about 50 fields built for a desktop experience and I just spent 3 hours trying to reposition 5 controls because everything takes 5 minutes to move and on some occasions doesn't even move where it should and each time I have to wait on "Please Wait".

totally agree with this post.!! i have the same issues. my application follow all best practices regarding performance, etc, but is a fact that the problem is because the amount of controls or pages in my app.
the main point is the application run perfect when is published, so, i think microsoft should delivery a better tool to develop this low code. (desktop app or a more robust app web editor)
