Why Most Power Apps Feel Slow (It’s Not the Platform)
Most slow Power Apps aren’t a platform issue — they’re a design issue.
Apps usually start off fine… then slowly get worse.
Longer load times, laggy clicks — just frustrating to use.
The tricky part?
It’s almost never one big problem.
It’s a bunch of small things stacking up.
Common Causes of Slow Power Apps
Here are some of the biggest ones I’ve run into:
1. Loading Too Much Data
It’s easy to pull in everything, but that slows things down fast.
👉 Only load what the screen actually needs.
2. Too Much on One Screen
Trying to do everything on one screen makes it heavy.
👉 Break things into smaller screens.
3. Overcomplicated Formulas
When formulas stack on top of each other (especially with lookups), performance drops.
👉 Simpler formulas usually run faster.
4. Repeated Data Calls
Calling the same data source over and over adds unnecessary load.
👉 Pull the data once, store it, and reuse it.
5. Ignoring Delegation
If your app isn’t returning all the data you expect, it’s likely not performing well either.
👉 Pay attention to delegation warnings early.
6. Everything Runs on Load
When everything fires at once, users are stuck waiting.
👉 Spread logic out instead of doing everything upfront.
7. No Feedback to the User
Even small delays feel worse when nothing is happening.
👉 Add loading indicators or simple feedback.
Final Thoughts
None of this is complicated.
But when you’re building fast, it’s easy to miss.
Fixing even a couple of these can make a noticeable difference in how your app feels.
