Mozilla promises: Firefox 58 will bring unexpected speed

Mozilla reports that Firefox 58’s new compiler and streaming compilation feature will make pages load faster. Mozilla promises that upcoming Firefox will further increase the load speed, a new engine (called Quantum) introduced in Firefox 57 that makes better use of multicore CPUs.

When compiling WebAssembly code, Firefox 58 compiles faster, thanks to “streaming compilation (which allows parallel compilation and download of code) and faster two-tiered compilers.

Lin Clark, an engineer at the Mozilla development team, said that streaming compilers and dual-layer compilers eliminate the bottleneck of slow page load by enabling Firefox 58 to compile code faster than the network can deliver packets. In the past, the network performance was limited by the network, especially the CPU and the main line, Firefox to reduce the burden on the main thread, make better use of the CPU time.

The stream compiler in Firefox 58 will make it faster for browsers to load WebAssembly files than JavaScript files of the same size. At the same time, Firefox 58’s two-tier compiler optimizes code compilation time when compiling the non-optimized code.

Firefox 58 is currently in beta and is scheduled for release on January 23, while Mozilla hopes the latest release will attract more former users.
