Google and their developers say you should test the performance and get as close to 60fps as possible, but the tool seems to be broken, or they do a shitty job too:
- Visit
google.comand find something - Open Chrome Development Tools,
- Go to the timeline → click record (Black dot on the left)
- Scroll Results Page
- Stop recording
- Be surprised.
Even if it is a page without any fancy animations or heavy JS, the timeline is red and it says:
Long time frames are an indication of jank.
Why is this. Does google have some interface issues, or does the recording tool not work?
