So last time I looked at this was some time ago, but the thing I was
missing then seems to still be missing: actual real numbers.
And no, I most *definitely* do not mean the pointless "do this in a tight loop".
That's just garbage. Honestly, when I see those numbers it just makes
me go "I don't want to merge things that even mention this kind of
stupid load". It's worse than irrelevant - it's an actively
misleading.
So I want to see a real load where this is actually visible not a
"loop a billion times on a hot-cache thing that doesn't do anything".
