Regression became visible immediately after the 1.29.0-wmf.14 roll out to group2 on 2017-03-02
p95 went from 5ms to 15ms. Minutely max went from wiggling between 500ms-1s to being between 1s-1.5s.
This is especially notable because this happened in the same release that also fixed T158813 which universally improved build times for the majority of modules, and yet this one regressed somehow - quite consistently and significantly so.
