make Firefox faster (lemmy.world)

I want to get more points in speedometer 3 using firefox. I've seen results above 20-24, but I can't get more than 12 because js takes a long time to process. What to do? Rebuild firefox with the -0fast flag?? Or do something with config. I use some fixes in it which just extend limits for everything (almost)

Any suggestions are welcome

@waz @soaska There are other reasons to be cautious about using AVX - older CPUs that support it are forcibly downclocked when the instructions are used so you'd better make sure that your vectorised loops are delivering enough benefits for the 10-20% penalty for all the rest of the code

Ohh, cool. Thanks for the warning. This just got complicated enough that I am definitely going to have do go down this rabbit hole.
