For Windows users this is no exception. The latest versions of Chrome for Windows has utilized Microsoft’s own PGO (Profile Guided Optimization) to increase page load speeds up to 15%.
What is PGO?
PGO, in technical terms, is:
a compiler optimization technique in computer programming that uses profiling to improve program runtime performance.
In terms I can understand, PGO takes the lesser used functions of a program and reduces the code used to implement said function. In turn, it optimizes the more highly used functions for speed.
The end result for Chrome is faster load time as the lesser used functions are given lower priority so that the more necessary code may be given a boost.
The chart below shows test results from Chrome on Windows 10 64-bit. The increases aren’t earth-shattering but they will definitely be noticeable.
Chrome for Windows 10 64-bit has been taking advantage of PGO Technology since the release of version 53 in August. Windows 10 32-bit followed in Chrome version 54 which arrived this week.
