I really don’t think they’re giving this a fair treatment. From what i gather, they switched from Muon which looks to be an Electron that uses later versions of Chromium. This version also had a custom UI written entirely in web technologies. They’re comparing that to their new version based directly on the Chromium code base + some privacy related patches. Their UI changes are now mostly relegated to a bundled extension so it looks and feels like Chrome. It seems they could have dug a bit deeper to find out where the speed up actually came from. The chromium build system is incredibly complex but very specially tuned to produce maximum performance for a specific configuration (Google Chrome Branded Release). When you go in trying to use bits and pieces of Chromium as dynamic libraries, things can go south rather quickly for performance. It could also mean that GPU acceleration or sandbox configurations differed between their modified Chromium versions they’re comparing here. Was LTO enabled on both builds? Either way, It feels like they’re taking claim for developing some browser performance increase of what is in all likelihood solely attributable to the Chromium project.
