Victor, do you know if you or anyone else has compared the RHEL/CentOS 7.x binaries (Python 2.7.5 + patches, built with GCC 4.8.x) with the Fedora 25 binaries (Python 2.7.13 + patches, built with GCC 6.3.x)? I know you've been using perf to look for differences between *Python* major versions, but this would be more about using Python's benchmark suite to investigate the performance of *gcc*, since it appears that may be the culprit here.
