Definitely Option B, that's the most straightforward way to optimize the code.

Option A seems like it would just add more complexity, I'd go with Option B.

Haha, I bet the app is running slow because the realtors are too busy scrolling through their social media instead of using it.

I feel like I need to double-check the logic in the OnStart code. It might be causing the app to load too much data at once.

I'm not entirely sure, but I feel like we had a similar question about performance issues in our practice tests. Maybe it's about reducing the number of calls?

I remember we talked about optimizing OnStart properties in class. I think it might be related to how data is loaded.
