Does anyone know why Firefox/Servo are so slow compared to the rest?

Mozilla's "privacy" image prevents them from knowing what their browser actually does in the wild, while Google collects CPU time profiles from user devices, comprehensively, and hammers down the hotspots they find, and that refinement has been going on for many years.

That’s nonsense. Firefox has telemetry built in, it’s just that you can opt out of it. Your answer doesn’t explain why at all but instead just takes a wild guess at what might have happened. You don’t know if this was discovered in Chrome or in some other use of V8. Or maybe it was always fast in Chrome! What a weird non-answer.
