point is, it is very hard to measure. it can make a difference, but no
reliable real-world benchmarks exist, afaik. its very much a matter of
opinion, after all...

Benchmarking is hard and people use it to lie a lot. On the other hand, though, the reason people do inlining, usually, is to improve performance, so you'd think that somebody pushing reduced inlining would have done some kind of performance study to see if the changes hurt performance unacceptably.

In other words, I'm not concerned about whether the experiments are scalable or universally applicable, but it would be interesting to know whether it had had any observable effect on whatever ingo chose to observe.

I'd be especially interested in things like interrupt latency, which I would expect Ingo to be well-prepared to measure.
