New submission from Ken Jin <kenjin4096 at gmail.com>:

Somewhere between May02-May11, dulwich_log benchmark on pyperformance had a major performance regression on the 3.10 branch. https://speed.python.org/timeline/?exe=12&base=&ben=dulwich_log&env=1&revs=200&equid=off&quarts=on&extr=on

For a start, we could git bisect with pyperformance. FWIW, I couldn't reproduce the perf regression on Windows. So it might be a Linux-only thing.
