Performance Improvement When Starting App

[mogulman]

This is an FYI.  I'm working on my first app.  I'm using an On-Premise SQL Server.  I've been for ways to improve performance.  I'm using collections and optimizing views.  I'm using SQL Profiler to check and measure performance.  I found one thing I wasn't expecting.  The Details and Edit screens use Lookups for the Item property.  When the screens load it executes the Lookup even though no Gallery item property is selected.  I have 4 main tables so 8 useless queries.  I added this to avoid the query.

If(!IsBlank(varClientID),LookUp('[dbo].[ClientVDT]',ClientID = varClientID))

It only saved me 300ms so not earth shattering.

Thanks for the feedbacks.

Actually Staff Mehdi Slaoui Andaloussi posted a blog talking about this:

Performance considerations with PowerApps

Which shares the query detail when Data (or saying the App) is loading.

I actually read that article in detail before starting my efforts.  He didn't cover the detail I discovered so I thought I would post it.
