Details

(Keywords: meta)

Metabug for experiments related to the performance of JSAtoms in the engine. This includes the performance of atomization itself as well as revisiting when atoms should be used. This also includes related issues around non-atom strings since there is a lot of overlap.

Atomization performance is also involved in our megamorphic property behaviour in React applications since we need atoms for property lookups.

This is the area we/I believe are relevant to speedometer and worth a narrow focus on, setting priority to P1
