The Linux 6.1 kernel in December last year brought a feature called Multi-Generational Least-Recently-Used (MGLRU), which is claimed to optimize the page recycling mechanism and improve performance under heavy memory load conditions. Improve performance.
According to the latest findings from Android tipster Mishaal Rahman, MGLRU is enabled by default for all Android 14 kernels (android14-5.15 and android14-6.1). The kernel of the Google Pixel 8 series is based on android14-5.1 GKI and is the world’s first phone to enable the MGLRU function by default.
Mishaal Rahman said that Google’s benchmarks show that after enabling MGLRU, the overall startup time of the app will improve, the number of overall process deaths will decrease, kswapd CPU usage will decrease, and so on. Next-generation flagships with Qualcomm and MediaTek chipsets should also have this feature enabled by default.

According to Google’s demonstration at the 2022 Linux Plumbers conference, after turning on MGLRU on the Pixel 6 phone:
Overall app launch time reduced by approximately 6.60%
Overall background killing decreased by 8.04%
kswapd CPU usage reduced by 54.50%
Direct recycling times reduced by 81.10%Users can use the adb command to check whether their phones enable or support MGLRU:
