firefox: significantly slower than Mozilla's .tar release

[noarchwastaken]

Is this a new report?

Yes

System Info

Void 5.19.10_1 x86_64 GenuineIntel uptodate rrmFFFFFFFFFFFFFF

Package(s) Affected

firefox-105.0.1_1

Does a report exist for this bug with the project's home (upstream) and/or another distro?

No response

Expected behaviour

The firefox package should run about as fast as the one from mozilla.org.

Actual behaviour

I tested the two different builds of Firefox:

• With entirely new profiles
• With my daily profile that has anti-fingerprinting tweaks and loaded with addons

And the package from Void repository runs consistently slower than the "Official" release, both in synthetic benchmarks:

and in subjective terms, such as pages loading slower.

Steps to reproduce

1. Install Firefox from the firefox package as well as from https://www.mozilla.org/en-US/firefox/all/#product-desktop-release
2. Browse the web and pay attention to performance differences

Got curious, decided to test it for myself.

VOID XBPS

MOZILLA

(both tested with my default fat profile)

I personally don't notice the difference in day to day use, and this is my main browser (in this day and age, that means most of my computer use happens in it) and it has a nice bag of plugins.

I guess there is some difference, but I am not sure what/how to investigate (maybe start with the patches that Void adds).

P.S. here is the benchmark website https://browserbench.org/Speedometer2.0/

Yes, we don't have enough build resources to do profile guided optimizations.
