Mozilla’s Firefox 58 browser, to be released January 23, features a compilation technology designed to make the WebAssembly portable code format run even faster.
This performance boost is enabled by streaming compilation, in which the browser compiles WebAssembly code even as it is being downloaded. Code begins compiling sooner and thus finishes executing sooner. Firefox 58 also features a new two-tiered compiler, with a new baseline compiler that compiles code 10 to 15 faster than the optimizing compiler.
Developers who use Firefox Nightly or beta can try out the technology on their own device at this link.
