Do rows in other apps make apps slower?

When a user enters your app, they should only interact with the rows tied to that app.

There’s a bunch of things that contributes to this, some of them being:

  • Try to use relations instead of queries where you can. Queries on large datasets can significantly slow down performance.
  • Compress images: Large images take longer to load, especially when you have them on the first tab the user’s going to load when they enter the app.
  • Use row owners: This limits the amount of rows the user needs to “download” when they use the app. Less rows = less calculations needed, so it also helps.

A good write up from Jeff here.
