The item where we take a significant performance hit is Python, and that's going to opt-out: https://src.fedoraproject.org/rpms/python3.11/pull-request/95 For what it's worth, frame pointers are required on other operating systems for precisely this reason. Linux is the odd duck out and it causes us many problems for real-time profiling, performance analysis, and other development tasks. If you want more performance gains, you need to be able to observe real workloads in real environments and see where the bottlenecks are. I'm confident that over the course of the next year, we'll recover performance that was lost by FORTIFY_SOURCE=3 and frame pointers as technology improves and we get used to having these by default. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
