docs about perfetto/ui about perfetto HOT 2 CLOSED

Hi,
sorry we don't have any good docs about the UI architecture. We are also in the process of changing it. I know it's complicated.

1、When i load a new trace file , how trace data parsed and flow between entire app. Too much controllers and message channel.

The short version is that all the data is parsed by the C++ code under src/trace_processor, which is wrapped in a WASM module.

2、Every time when i modify files and reload the browser , that cost too much time waiting to show.

Yes, UI builds, even incremental change, are O(several seconds) slow. Patches to make it faster are welcome.

Closing as there seem to be no bug / nothing actionable.
If you have specific questions ask them on the discord channel (see the contributing and community guide on https://perfetto.dev)
