I regret to say that I can't reproduce my initial result showing 9% improvement on 3.2.0rc1 against 3.0.4. Both versions show the same speed now.
I also compared 3.0.4 against trunk in another environment: Ubuntu 18.04.2 LTS (GNU/Linux 4.15.0-1014-gcp x86_64) cpu model name: Intel(R) Xeon(R) CPU @ 2.00GHz This is the raw result from 3.0.4: 640 Examples seen.
