That's the first time I have heard a number this high for these exploits. All prior numbers I've heard were many orders of magnitude smaller, more like byte/s. The article linked above cites 1 kB/s as novel.

That was a number I heard (Meltdown pre-mitigations) when the "oh shit" papers started dropping a few years ago, could be misremembering. I'm also still slightly inebriated so thank you for nerdsniping me (Lit Review time!)
