Audit performance of the various DevTools screens and components #5091
Description
A common concern raised by some Dash engineers is that DevTools often feels slower than existing tooling in Observatory.
Some examples of scenarios with poor performance:
- Opening DevTools while connecting to a CLI application automatically fetches and loads a timeline, locking up the UI thread until the timeline is fetched and processed
- Poor performance when creating filtered CPU profiles
Performance of the various tools should be audited to ensure that current power users of Observatory do not experience a degradation of their development workflows.
This is a blocker for deprecating and removing Observatory from the Dart SDK.
