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

I’m guessing you’ve already happened across this, but in case you haven’t, here is an explanation of the the compilation flags thorium uses for it’s chromium builds:

It seems as good of a place to start as any.

I haven’t spent a ton of time down this particular rabbit hole, but now I may have to.

@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
