Regarding PGO benefits for Firefox, there is a thread:
https://groups.google.com/g/mozilla.dev.platform/c/wwO48xXFx0A/m/ztg4i0DYAAAJ
that shows measurable improvements from PGO.
Anyway, since the issue is quite old. Is PGO still disabled for Firefox
in Ubuntu repositories? Maybe things have
I'm backing this out of quantal. The benchmarks show negligible benefit
of turning on PGO in most tests, and there isn't really any perceivable
difference at all - certainly not enough to justify a 100% increase in
build time

Chris - thanks for your efforts on this. I am a little surprised to
hear that the benchmarks show negligible benefit of turning on PGO in
most tests, given what I have read previously in this bug and in the
Mozilla bug reports. However I am not an expert so I guess it is
possible. I just have
Yes, the build system automatically sets that when you build with PGO

I'm turning this back off again due to continual build failures that are
only reproducible on the buildd's, and because the the PPA builders are
pretty much incapable of building it to help investigate

Actually, scratch that. We get the same build failure in thunderbird

You're getting a bit ahead of yourself, it hasn't even built in quantal
yet. Perhaps ask me again in 4 months when it's had some proper testing
there first

@Sam Tygier - re comment #135 - unless I am understanding what I've read
in the Mozilla bugs incorrectly, -Os seems to be an alternative to

Firefox' Linux release builds have been using PGO for some time now. The
difference is quite noticeable, especially on slow systems, such as
netbooks. Why is this not used by Ubuntu yet? Firefox is Ubuntu's
standard browser and users should have the best experience possible.
