STINNER Victor added the comment: Results of the CPython benchmark suite. Reference = default branch at rev 496e094f4734, patched: fastcall fork at rev 2b4b7def2949.
I got many issues to get a reliable benchmark output: * https://mail.python.org/pipermail/speed/2016-April/000329.html * https://mail.python.org/pipermail/speed/2016-April/000341.html The benchmark was run with CPU isolation. Both binaries were compiled with PGO+LTO.
