IIRC Fedora has always not been the top performer in Phoronix benchmarks anyway, so we can't really attribute that to just frame pointers.
For frame pointers, this might be a better comparison -- RHEL 10 vs Rocky 10 vs Alma 10. The former two don't have frame pointers enabled, the latter does. As you can see the performance is within margins of error - Alma is not consistently the slowest and sometimes is the fastest. https://www.phoronix.com/review/almalinux-10-rocky-linux-10/2 Best regards, -- _o) Michel Lind _( ) identities: https://keyoxide.org/5dce2e7e9c3b1cffd335c1d78b229d2f7ccc04f2 README: https://fedoraproject.org/wiki/User:Salimma#README -- _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org 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@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
