## 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.
