Google Chrome is up to 15% faster, thanks to Microsoft

Google Chrome loads up to 15% faster on Windows thanks to Microsoft's 'PGO Technology'

Google Chrome has received some performance improvements applied, with help from Microsoft and its PGO technology that makes Chrome's startup time around 17% faster. Chrome now loads web pages 6% faster and is 15% faster with new tab loading times.




Microsoft's PGO technology is 'Profile Guided Optimization', which measures just how users use the application, and then with this data in-hand it will re-compile an application that focuses on optimizing the most-used functions. Another feature of PGO is that it speeds apps up by keeping the most-used functions inside of the CPU's fast instruction cache.


Google took to the Chromium Blog, explaining in a new article called 'Making Chrome on Windows faster with PGO'. The team added: "To gather this data, the nightly build process now produces a special version of Chrome that tracks how often functions are used. PGO then optimizes those high-use functions for speed, in some cases increasing the binary size of those functions. To balance out that increase, PGO also optimizes less-used functions with smaller, though slightly slower code. These trade-offs result in higher overall performance, and a smaller overall code footprint".


Not only that, but "PGO also optimizes the memory location of the code, moving rarely-used functions away from frequently-used ones in memory. This results in more optimal use of the CPU instruction cache by avoiding caching of less-used code, increasing overall performance". The blog also links to many other tricks that "PGO uses to make Chrome faster, and they add up to great results".
