Google is messing with Android. Phones will noticeably speed up

The system kernel is the most important element of Android. It is responsible for communication between the processor, applications and hardware. According to information provided by Google, this item consumes approximately 40% of CPU time on mobile devices. Even minor modifications in this area produce visible effects in the operation of smartphones.

The giant from Mountain View has implemented a technology called Automatic Feedback-Directed Optimization (AutoFDO). This tool analyzes data from real device usage. Typically, the compiler converts software code into instructions understandable by the processor based on general rules and assumptions. The new feature completely changes this process.

The compiler now learns from real life scenarios. Google collected the necessary data during laboratory tests on Pixel series phones. Use was simulated there the hundred most popular applications for Android. During this time, special tools tracked the fragments of kernel code used most often by the system.

The software recognizes intensively used areas. The system kernel is then rebuilt using this information. The compiler better organizes the layout of the code and optimizes its operation. Frequently called functions therefore run with much higher performance.

The optimization used brings tangible benefits to equipment owners. Applications launch noticeably fasterand switching between open programs takes less time. The entire operating system runs smoother. The overall operating time of the device on one battery charge also increases.
