Benchmarking Mercury As The "Fastest Firefox Fork" With AVX, AES, LTO + PGO: Following the news last week of Firefox outperforming Chrome in SunSpider, a Phoronix reader pointed out Mercury that is an open-source web browser claiming to be the "fastest Firefox fork" and making use of Advanced Vector Extensions (AVX) and AES instructions along with compiler features like Link-Time Optimizations (LTO) and Profile-Guided Optimizations (PGO). The project advertises as being 8-20% faster than upstream Firefox. Curious I ran a couple benchmarks on my end of this Firefox fork.
