I’m still wondering how can I set up Fennec to be that fast as Iceraven.
Nothing changed results. JIT, webrender etc… it’s indeed so complex that I can’t compare all settings but I’ve checked basic things and see they are the same they do not do the same. Iceraven in Speedometer test, and in everyday usage is faster (test shows like about 20%).
I can confirm that the official build of Firefox 144 show 15% better score in Speedometer 3.1 than Fennec 144 (357 vs 310 on my test device with Snapdragon 835 and Android 15).
The detailed results show that all tests are roughly 15% slower in Fennec, so it’s not just a few tests that spoil the total score.
I also compiled Firefox 144 myself following the official instruction and it scores the same as Fennec. So, there should be some configuration options that make official Firefox faster.
Update: might be PGO: Profile Guided Optimization — Firefox Source Docs documentation
Im testing Cromite.
It makes much more decent results with WebGL and JIT enabled than it makes with disabled. Checked and they are enabled on both Fennec and Iceraven so I can’t understand where such the difference comes from.
I’ve screen shoot task manager for easier comparison. 
how is that even relevant here? pfft
