Information about Loading efforts in Chromium
Last updated May 2021
Loading on the web is user centric, sustainable, fast and delightful.
- user centric: the experience is described through key user moments or needs, and assessed against a perceptual model of performance.
- sustainable: a sensible contract between Web developers, UA and users about how a web application loads, with usage of memory / power / data that is proportional to value.
- fast and delightful:
- Meet the Core Web Vitals thresholds
These are the goals we should strive for.
Some aspects might be extremely challenging but making progress toward these is what should drive our work.
How do I find out what's happening?
- Communications: email@example.com is our public discussion group for all things related to Loading in Chrome.
- crbug: blink
I have a reproducible bad Loading user experience, what do I do?
As a user:
- File a Speed bug
- Include the "Loading" keyword in the subject if the issue fits within the scope of the North Star.
- If you are not sure, don't include the "Loading" keyword, triage will make sure it shows up in the right bucket.
As a chromium developer
- Same steps but try to record a trace (select every trace categories on the left side).
