I do not particularly enjoy self-flagellation, but I think that besides some conscious system-wide choices that could measurably affect performance for everyone (e.g. compiler flags), we suffer from a lack of interest towards bugs that happen behind the scenes and impact a subset of our users. Even in cases when upstream is aware of an issue and a fix is promptly made available, in some cases it never finds its way to a supported Fedora version or that happens with a considerable lag. In the last 4 or so years I remember issues with tracker, gnome-shell, mutter/clutter and friends on specific GPUs, default or popular shell extensions and dbus services. A recent bug which is also related to the topic of Jim Salter's article is #1916652. SELinux and Flatpak are supposed to be first-class citizens in Fedora, yet we get bugs like that. There has been a flatpak update in the interim, but it didn't address the problem. And while on a 16-core system this barely registers (unless someone has SELinux Troubleshooter installed), I reproduced it on a dual-core Celeron and it took almost five minutes to get the system to a usable state. _______________________________________________ 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
