Hi all, Spending an hour with "hg bisect" is a good way to figure out some of the worst speed regressions that occurred in the early days of 2.7 (which are still not fixed now). Here's my favorite's pick: * be4bec689de3 made bm_mako 15% slower, and spitfire_cstringio even much more * ad030571e6c0 made ai 5% slower Just thought it would be worth mentioning it here. There is much more waiting for someone with a little more patience if we believe https://www.speedtin.com/public . A bientôt, Armin.
