That's not really useful for understanding and making progress on the issue.
Uh, it kinda does actually. It's highlighting that a better hash function will only have a minor effect. The time sink is the number of instantiations that are happening.
But it is worth pointing out that, yes, for you to see the problem here you won't see it with simple tests. Binderoo very quickly builds up recursive template instantiations that bring the problem out from the crypt and in to the light.
