Unfortunately, no, it's a commercial closed-source project. I profiled both JS and WA versions, the hottest methods took basically the same amount of time in both versions, except that WA build additionally spend ~25% of all time in __retain or something like that.

Do you intensive use small objects like Vec3, Quaternion and etc? AS hasn't scalar replacement optimization pass yet which JavaScript definitely has. Also it will be much better after implementing tuple / records which depends on multi-value proposal for now. All this significantly reduce ARC / memory pressure. But my assumption it could be also wrong measurement. Most of people uses benchmark.js which also measure js <-> wasm interop overhead which usually main bottleneck.

Yes, I do use a lot of small objects. That's an interesting information, I'll keep an eye on multi-value proposal, thank you!

Nope, I loaded all the data into WA module upon initialization and don't perform any additional synchronization between WA and JS afterwards (which is also kind of unfair advantage for WA).
