Mozilla can produce near-native performance on the Web
BTW, C/C++ code that is compared has multithreading and SIMD capability disabled. In the third page they benchmark asm.js and native with multithreading and SSE enabled. It shows upto 50x slowdown! Not exactly sure what the point of a benchmark without multithreading is. I mean anyone writing performance sensitive apps will use MT right? (given JS is single threaded, it seems this is a dealbreaker).<p><a href="http://cdn.arstechnica.net/wp-content/uploads/2013/05/classic-native-v-optimized-v-asmjs.png" rel="nofollow">http://cdn.arstechnica.net/wp-content/uploads/2013/05/classi...</a>
