Do we need a bug report? Post to devel@ or desktop@ lists, is my advice. If you convince Workstation edition folks, it'll certainly get more attention on devel@ once it's a feature/change request. It might be appropriate to set dirty_bytes to 500M across the board, desktop and server. And dirty_background to 1/4 that. But all of these are kinda rudimentary guides. What we really want is something that knows what the throughput of the storage is, and is making sure there isn't more than a few seconds of writeback needed at any given time. The default, dirty_ratio 20%, is high by today's memory standards. But upstream will not change it. All kernel knobs are distro responsibility to change from the defaults. I'm the first person to poo poo benchmarks. But if you run all of them, it should be pretty easy to show whether it's generally useful, or generally not useful (i.e. either bad or ambiguous) to change it. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-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/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
