Google announced it was retiring its Octane JavaScript benchmark, saying most of its tests are outdated and contained bugs that allowed browser developers to cheat and obtain higher scores than intended. The search giant said that Octane’s tests no longer reflected the best way to measure performance in modern browsers, and the way websites load and execute JavaScript code. Google says it improved page load times in Chrome by 10-20%, based on “real-world performance data”” Google has developed a set of new tests that it uses internaly and which work by loading snapshots of various websites.”
