Speed has always been Google Chrome’s main selling point. And now, Chrome for Windows is faster than ever, thanks to Microsoft’s Profile Guided Optimization (PGO) that makes Chrome run about 15 percent faster than before on Windows.
Starting with the 64-bit Chrome 53 and 32-bit Chrome 54 on Windows, the internet juggernaut has started using Microsoft’s PGO technology that boosts the speed of Chrome startup time by 16.8%, new tab page load time by 14.8%, and overall page load times by 5.9%.
Profile Guided Optimization is an attribute of Microsoft Visual Studio developer tools, which evaluates how users actually communicate with an application. Using those data, it then re-compiles the application with a focus on optimizing the most frequently used functions of the applications.
“Chrome is a huge software project with more than a million functions in its source code. Not all functions are equal – some are called frequently, while others are rarely used. PGO uses data from runtime execution that track which functions are most common to guide optimization,” said Google’s Sébastien Marchand.
PGO optimizes the memory where the frequently-used functions are kept, which is one of the most feasible techniques to speed up applications. 32 bit Chrome is just now taking the advantage of PGO in the latest version, while 64 bit Chrome has been using it for Windows since version 53. You can download the latest version of Chrome for Windows or check the version as the browser updates itself automatically.
