STR: Load www.amazon.com. There is a function named j() ran from the root scope of amazon.com very early at page load under this stack: j (root scope) https://www.amazon.com/ (root scope) https://www.amazon.com/ This takes a surprising amount of time. 34ms in https://perfht.ml/2peN9L2, 22ms in https://perfht.ml/2peDjsB. This is part of the Quantum Release Criteria. We should try to make this function as fast as possible.

Naveed, can you find an owner for this please?

Ehsan, do you still see "function j" on line 1847? I checked locally but that line is empty here, they probably changed the website and/or I'm getting a different version. It would be interesting to see what this function is doing.

I think they have changed the website... :-/ I couldn't capture something similar again... :-/
