Performance things to investigate

[wcjord]

• We see _handleRoomSync showing up a lot as it should. However, there may be some downstream optimizations here. Like, does chat.dart setState for room_ids of events coming in not in that room? Only the chat_list item associated with an incoming event should change.
• Can we send or receive less presence updates?
• others?

@ggurdin for you to add to and maybe take notes on here

From heap snapshot in chrome memory tab after login. Took three snapshots, the first before login, the second immediately after login, and the 3rd a few seconds later.

The variable shown here (with the greatest increase in heap size between the 2nd and 3rd snapshots) seems to be a list of events.

The object with the next largest amount of allocated space is a list of events. The next highest is a map, but I'm not sure exactly what it's a map of. Here's a screenshot of some of its contents:

Next is a list of choreo record steps:

Most of those are token events no?

[ggurdin]

Yes, looks like it

From dart devtools on my android device. First one is a test account, others are from Will's prod account

Screenshots from class on 7/17. Timelines seem to be continually created but not garbage collected:

I'm going to close this general ticket. We can open more specific performance-related issues as we identify them.
