Actually, the long-running fuzz test may be IO-bound so using a ramdisk could speed them up. So this would be another idea to look at.

ACK 06a7df70df30879e0b691d1a252636f703b8cdfb, I've backported the listed PRS locally. The only merge conflict I faced was in https://github.com/bitcoin/bitcoin/pull/30807. It was trivial to resolve.

Could rebase on current master, now that the header generation is 30x faster, after 2a0949f0977db2dbb7ac452e8d58d413b9526756 ? This should also change the benchmark in the pull description.

ok. is C++20 a requirement? why? it's not fully supported by clang or gcc yet. can get 90% there with libstdc++ , but I guess it's only a matter of time.

(https://github.com/bitcoin/bitcoin/pull/30666#discussion_r1763467219)
I thought about it a bit and don't see a great non-invasive solution to this: We could add a call to `NotifyHeaderTip` in the calling functions after `cs_main` is released, which would be in `ActivateBestChain()` (plus in the `invalidateblock` / `reconsiderblock` rpcs which seem less important), and I'm unsure if we want to refactor this function to always call `NotifyBestHeader()` just for the special case where a connected block turns out to be invalid.
In any case, since `m_best_header` is

will change to "/" so it mirrors the "invalidation / reconsideration" in the line before.

Did a significant restructure, the tabular tests should be a lot easier to comprehend and modify now.
I still need to get rid of remaining flags in the tests, will do that tomorrow - any early feedback until then is appreciated.
