STINNER Victor added the comment: I ran the Python benchmark suite on wpy6.patch.
* My platform: Linux-4.4.4-301.fc23.x86_64-x86_64-with-fedora-23-Twenty_Three * My PC: CPU Intel i7-2600 (~2.9 GHz) with 12 GB of RAM * Benchmark ran on isolated CPU: http://haypo-notes.readthedocs.org/microbenchmark.html * Command line: ~/bin/taskset_isolated.py time python3 -u perf.py --rigorous "$ORIG_PYTHON" "$PATCHED_PYTHON" -b all 2>&1 It looks like we get more faster benchmarks than slower benchamrks. Faster is up to 11% faster, whereas the worst slowdown is only 4%. The overall results look good to me.
