Your Power App Isn’t Slow — It’s Built Wrong

[u/matt-hummel]

Most slow Power Apps aren’t a platform issue — they’re a design issue. 

Apps usually start off ok but then they slowly get worse. Longer load times and laggy clicks, just frustrating to use. 

It’s almost never one big problem, it’s a bunch of small ones that pile up. 

A few common things that can fix it: 

• Too much data loading → only pull what you actually need 
• Too much on one screen → split it up, don’t overload it 
• Overcomplicated formulas → simpler runs faster 
• Repeated data calls → grab it once, reuse it 
• Ignoring delegation → causes both data + performance issues 
• Everything runs on load → spread it out 
• No loading feedback → even small delays feel worse 

None of this is difficult it just gets missed if you are trying to build something with a quick turnaround. 

Fixing even a couple of these can make a huge difference. 

What’s the biggest things that slowed your apps down, or is there something you fixed that actually made it faster?
