Thank you for looking into the potential issue. Instead of getting Python3.8 from ppa:deadsnakes/ppa, I downloaded the source from: https://www.python.org/ftp/python/3.8.0/Python-3.8.0rc1.tgz Then did the following to build and install it: $ cd /usr/src $ sudo tar xzf ~/Python-3.8.0rc1.tgz $ cd Python-3.8.0rc1/ $ sudo ./configure --enable-optimizations $ sudo apt-get install zlib1g-dev $ sudo -H make altinstall Then re-running the magiccube2x2 permutations with a max_depth of 6 I obtained: $ python3.7 permutations2x2 --max_depth 6 | egrep "^# Total_Time" # Total_Time: 61.90 $ python3.8 permutations2x2 --max_depth 6 | egrep "^# Total_Time" # Total_Time: 82.45 Unfortunately, this still shows the Python3.8 execution as significantly slower, in this case 33.2% slower. Not sure of the cause, but perhaps I wasn't completely successful at removing the prior installation from ppa:deadsnakes/ppa. I removed it through the use of: $ sudo apt remove python3.8 $ sudo add-apt-repository -r ppa:deadsnakes/ppa $ shutdown -r now Next step I will completly re-install this server and then only install Python3.8 from https://www.python.org/ftp/python/3.8.0/Python-3.8.0rc1.tgz. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38477> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
