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.

Even if true (and I agree with sibling that I don't think that it is), base64 encoding/decoding feels like one of those things you'd have a micro benchmark for regardless. It's also shocking that the gap is so wide, as I feel like people working on such things would start with a fairly optimized v1.

I wonder if this is why Firefox feels so sluggish with some more complex SPAs.
