The microbenchmark David used is desribed in his email:
https://www.mail-archive.com/curl-library_at_lists.haxx.se/msg02593.html
The regression was discovered by a huge A/B test of a system overall,
that involves many machines, many hours and a ton of traffic. What
I'm going to do now is to re-run this A/B test with 8.16.0, to avoid
relying on year old data.
