Sorry this is a bit late, but here once again are the speedometer benchmarks. This time I made sure to include the package version.
I used a different computer than my first test but the conclusion is still the same: Firefox deb is beaten by alternative packages of firefox (in this case snap). Speedometer score (https://browserbench.org/Speedometer2.0/): Tested on Ubuntu 20.04.2 (ISO: ubuntu-20.04.2.0-desktop-amd64.iso) Firefox Snap: Score: 36.6±2.0 Package: 86.0-3 Firefox Deb: Score: 28.89±0.18 Package: 86.0+build3-0ubuntu0.20.04.1 For further research it may be useful to benchmark firefox deb vs firefox snap/flatpak in various tests, similarly to how phoronix compares chrome and firefox on linux (https://www.phoronix.com/scan.php?page=news_item&px=Chrome-89-Firefox-86). However, even though the speedometer score is evidently lower on the deb that doesn't mean it is necessarily an real-world issue. As noted by google when they retired octane as a recommended benchmark (tests javascript), web benchmarks can be misleading and can poorly represent real-world performance (https://v8.dev/blog/retiring-octane). The lower score on firefox deb may not correlated with a perceiveable performance difference. My opinion is that a fix for this issue is not worth putting considerable time into if we cannot demonstrate clear real-world performance deficiencies in firefox deb. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1908082 Title: Ubuntu Firefox is 15% slower than Flatpak Firefox for speedometer benchmark To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1908082/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
