[Bug 1908082] Re: Ubuntu Firefox is 15% slower than Flatpak Firefox for speedometer benchmark

[Olivier Tilloy]

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.
