Cool! I have an idea that, after we have this, we could further divide the 64bit version into two versions, e.g. one with basic 64bit, the other with more instruction sets enabled, so that more optimization could be done. If we would like to do this, we would probably need data including the percentage of users are on hardware supports each instruction set, and how much performance gain we would get for enabling each level of instruction set. It probably would turn out this isn't really worth the effort, though. I think it is at least worth benchmarking how fast a Firefox build with, e.g. AVX enabled, could be. - Xidorn _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
