## Information about Loading efforts in Chromium
Last updated May 2021
## **North Star**
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](https://web.dev/defining-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: loading-dev@chromium.org is our public discussion
group for all things related to Loading in Chrome.
* crbug: [blink](https://bugs.chromium.org/p/chromium/issues/list?can=2&q=component%3ABlink%3ELoader%2CBlink%3ENetwork%2CBlink%3EServiceWorker%2CBlink%3EWorker&sort=pri+-component&colspec=ID+Pri+M+Stars+ReleaseBlock+Component+Status+Owner+Summary+OS+Modified&x=m&y=releaseblock&cells=ids)
## I have a reproducible bad Loading user experience, what do I do?
* ## As a user:
* File a [Speed bug](https://bugs.chromium.org/p/chromium/issues/entry?template=Speed%20Bug)
* 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](/developers/how-tos/trace-event-profiling-tool/recording-tracing-runs)
(select every trace categories on the left side).
## I'm a dev and interested in helping on Loading. How do I get started?
Reach out via loading-dev@ and tell us more about you:
* share your particular interest and expertise
* tell us how familiar you are with chromium development
* point to CLs if not a lot of developers are familiar with your work
## Contacts
Your friendly PM: kenjibaheux
Blink TLs: kouhei, yhirano (blink>network)
