Public bug reported: This is not a bug, more of a degradation of performance report.
Going from Ubuntu 20 to Ubuntu 21 (and same on Ubuntu 22 pre-release), I noticed that C++ performance got worse, while it stayed the same for pypy: Ubuntu 21: pypy 1.419s 1.387s 8.527% 2.469% c++ 1.843s 1.719s 8.935% 2.465% Ubuntu 20: PyPy 1.410s 1.389s 8.463% 2.290% C++ 1.588s 1.507s 8.781% 2.284% details: https://www.frisky.world/2022/03/what-happened-to-c-performance-going.html software I use: https://github.com/pepe78/python-performance ** Affects: gcc-11 (Ubuntu) Importance: Undecided Status: New ** Tags: performance -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1965451 Title: C++ performance got worse going from Ubuntu 20 to Ubuntu 21 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-11/+bug/1965451/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
