Windows 10: Making Google Chrome on Windows faster with PGO

Brink · Oct 31, 2016

Chrome is always looking for ways to speed up the web. Starting in Chrome 53, Chrome has started using Microsoft’s Profile Guided Optimization (PGO) technology to make Chrome up to 15% faster on Windows.

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.

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.

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. There are many other tricks that PGO uses to make Chrome faster, and they add up to great results.

64-bit Chrome on Windows is using PGO as of version 53, and 32-bit Chrome is using it as of version 54. Try out the latest version of Chrome to see the difference with PGO.

Not sure what's new here. Successful program optimisation has always concentrated on improving the most heavily used code if you are coding for speed. If you are coding to reduce size that's a different matter.

is firefox or google chrome going to be available for windows phones - Nokia 920?

Also note that Chrome will stop using the WebKit engine in a few months..

No, Google will still use WebKit for Chrome, but they are making their own copy of it to benefit their browser faster.

Hello,

I do not use Internet Explorer as my main browser! I use Google Chrome which is faster and easier.

Does Google Chrome work under Windows 10?

Thank you!
