Description

On iOS, loading a chat room with lots of messages takes a while. I’m afraid that without any optimization here, it will only get worse with hundreds of people messaging in a single chat room (like the hallway).

This does not happen on the web.

Research direction

Reproduce the slowdown on iOS by opening a chat room with many messages, using the linked recording as the symptom reference, and compare it with the web behavior. No file, test, or entry point is named, so first locate the iOS chat-message loading path and profile it; done means loading is measurably faster for large rooms without regressing normal chat loading.
