These numbers are all Vs a completely unmitigated system. AND, this is an extra-expensive version of ASI that does more work than really needed on this HW, to ensure we can measure the impact of the recent changes. (Details of this are in the posting).

So I should probably post something more realistic, and compare against the old mitigations. This will make ASI look a LOT better. But I'm being very careful not to avoid looking like a salesman here. It's better that I risk making things look worse than they are, than risk having people worry I'm hiding issues.

Not sure if you wrote this article and I appreciate an engineering desire to undersell, but if this is faster than what people actually do in practice, then the takeaway is different than if it is slower, so I think you're doing folks a disservice by not comparing to a realistic baseline in addition to an unmitigated one.
