Performance Improvements for Sharepoint List Apps



I am getting very close to the finishing touches on an app.  It is currently driven primarily by a Sharepoint list that has 27 columns.  About half of those are single line of text, then a mix of yes/no date, and only one caclulated.  There are no lookups.


It is working fairly well, but I would like to make the response of my powerapp a bit more snappy.  I have the date shown in a Powerapp Gallery, with various search methods.  I was wondering if:


For Single Line of Text columns... does shortening the max character from 255 to a much smaller number make a difference?  Many of these fields, I only need a few characters.  I presume (please correct me if I'm wrong) but the typical width if 8's is what is important.  Thus, if I only need 6 characters, its no more expensive to put in 8.  Perhaps that only matter with stuff at a much lower level, but its the mode of thinking I would like verified.


Also, do number fields as opposed to text fields matter with respect to performance?  I can convert some of them one way or another if that matters.  


I'm open to any suggestions!


Thank you!

Hi @martinav,


How many items do you have in this list? Can you share the formula that you used on the Gallery's Items property? If it's a large list, the slow performance might be related to the delegation in PowerApps.
