With MGLRU, Google managed to reach a 40% reduction in kswapd (the process that controls virtual memory) CPU usage and achieved a decrease of 18% of out-of-memory (OOM) app killings.
What do these dry figures mean for us? Well, kswapd needing 40% less than it usually does means we will get more CPU time to run other tasks and apps. A decrease of 18% in out-of-memory app kills implies that it’s 18% less likely for Android to kill an app that may be important to you.
There is no word if indeed Google will release MGLRU with Android 13, but when it comes, this new feature no doubt will offer a better experience for all users of the OS.
