Performances are not great in general, bad on Firefox, on Chrome, well, it could be an improvement. Leave it as a fallback for now, but can be forced via project settings if desired (or custom JavaScript logic via the "args" option). I'm actually surprised this works, it involves so many allocations, but there's no way around it when SharedArrayBuffer is not available :(.
