Hello,
The timeline and flame graph features of Chrome's DevTools have been very
useful for us as we work to understand and improve the performance of
VisualEditor. Someone asked me today about how we use these tools, so I
recorded a short (3-minute) screencast. It unfortunately cut off near the
end, but only the last sentence or so got clipped.

T88590 is a good example of a bug we caught using this feature:

Hope it's useful,
