> I think it makes sense to not exceed that number, as having more threads than cores doesn’t really help.

This would make sense if RPCs are purely CPU bound. Many RPCs are mainly IO bound, and the OS can suspend a thread while it waits on IO. Absent coroutines that can suspend execution on the same thread for IO, more threads than cores will be a benefit.

Makes sense, similar change to https://github.com/bitcoin/bitcoin/pull/33485.

Would it make sense to lower the default only on 32-bit systems? We have lower maximum settings for dbcache and maxmempool on these systems as well, since they are more memory constrained.

I've removed some of the less impacting changes, considering @cedwies suggestions. It now shows a 9% improvement on CCoinsCache on my end (up from a 7.7% previously)

> now the code paths depend on each other

That's not the case, at least not with the latest push:

- `vSolutions` is used regardless of the code path. It's used before branching.
- `witnessprogram` is used late, after a couple of branches, but this can't possibly impact performance since `std::vector` starts allocating only after first use.

> Wouldn't reserving the vectors help here instead?
This was my initial intuition, but it actually goes against your previous point. `.reserve()` w

This PR does not seem to have attracted much attention from reviewers. As such, it does not seem important enough right now to keep it sitting idle in the list of open PRs.
