Similarly, I'm seeing better performance for the snap version of firefox than with the deb, on Ubuntu 20.10:
deb: 85.1 ± 1.4 snap: 108 ± 1.5 This could very well be explained by the toolchain and default build options used to build each package: the snap is built from an upstream binary, compiled with a very recent toolchain and likely many optimizations turned on, whereas the deb uses the toolchain available in the corresponding Ubuntu series, and often not with full optimizations to work around hardware limitations in the Launchpad build farm or toolchain bugs. This is not to say that we cannot research turning on more optimizations though. ** Changed in: firefox (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1908082 Title: Ubuntu Firefox is 15% slower than Flatpak Firefox for speedometer benchmark Status in firefox package in Ubuntu: Incomplete Bug description: Steps to reproduce: I installed Firefox Flatpak (https://flathub.org/apps/details/org.mozilla.firefox) and Chrome.
