[Python-Dev] Help requested with Python 2.7 performance regression

[Victor Stinner]

"faster" or "slower" is relative: I would like to see the ?.??x
faster/slower or percent value. Can you please share the result? I
don't know what is the best output:
  python3 -m performance compare centos.json fedora.json
or the new:
  python3 -m perf compare_to centos.json fedora.json --table --quiet
