STINNER Victor added the comment:
I'm not a big fan of pybench (it looks unstable and so not reliable), but here
are results with dict_version-4.patch.
I used more loops and a lower warp factor to get more reliable tests (I hope):
./python Tools/pybench/pybench.py -f pybench.orig -w 2 -C 100 -n 25
./python.patched Tools/pybench/pybench.py -f pybench.dictver -w 2 -C 100 -n 25
./python Tools/pybench/pybench.py -s pybench.dictver -c pybench.orig
