Firefox Developers Continue Tuning ASM.js Performance
Mozilla developers continue to optimize everything they can with ASM.js to deliver the greatest performance possible inside Firefox.
In a new Mozilla blog post its mentioned, "Firefox with float32 optimizations can run all those benchmarks at around 1.5x slower than native, or better. That's a big improvement from earlier this year, when as mentioned before things were closer to 2x slower than native." Additionally, "on some benchmarks, like box2d, fasta and copy, asm.js is as close or closer to clang than clang is to gcc. There is even one case where asm.js beats clang by a slight amount, on box2d."
