I don't know if this helps as a data point, but until 32, Fedora always "won" one of the bottom spots in Phronix distro comiparison benchmarks. However, starting with Fedora 33, at least on some hardware, we now outperform Ubuntu 20.20, Manjaro, and even Clear Linux - at least on average: https://www.phoronix.com/scan.php?page=article&item=fedora-wins-tgl Maybe I can provide some anecdata: In my experience, Ubuntu based VMs always felt way more responsive and faster than Fedora based VMs (I use them regularly to do QA for my Pantheon packages, since Fedora 2x or so.) But today, cold booting a Fedora 33 or 34 VM is more than twice as fast (~25s) compared to an Ubuntu based (elementary OS 5 / ubuntu 18.04.x LTS) VM (~68s), and when launching Firefox after a cold boot, Fedora 33 was almost exacty twice as fast (~25s vs. ~50s), again. For both of those "tests", Fedora 32 was a bit slower than either newer Fedora or elementary OS. Even if those are not "scientific" measurements, I did not expect the differences to be this big, but apparently, we're doing something right. :) Maybe switching on LTO by default did help - it was introduced with Fedora 33. The "Fedora is slow and sluggish" review you linked specifically mentions Fedora 32. Apparently the author has not tried Fedora since (there's no review of Fedora 33 on Ars Technica). And I would be curious to see whether upgrading to Fedora 33 would affect the result of the "launch Chromium snap" test in our favor ;) Fabio _______________________________________________ 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
