Google har lansert oppdateringer med forbedret implementering av LRU-mekanismen for Linux. LRU (Least Recently Used) \u2014 er en mekanisme som gj\u00f8r det mulig \u00e5 kaste eller bytte ut ubrukte minnesider. If\u00f8lge Google skaper den eksisterende implementeringen av mekanismen for \u00e5 bestemme hvilke sider som skal byttes ut, en altfor h\u00f8y belastning p\u00e5 CPU-en, og tar ofte d\u00e5rlige beslutninger om hvilke sider som skal byttes ut. <\/p>\n

I eksperimentene utf\u00f8rt av selskapet reduserte den nye implementeringen av LRU antall tvangsgenererte programkrasj p\u00e5 grunn av minnemangel (OOM-kill) med 18 %. I Chrome OS ble antallet kasserte nettleserfaner p\u00e5 grunn av utilstrekkelig minne redusert med 96 %, og antallet OOM-kill p\u00e5 overbelastede enheter ble redusert med 59 %. Dette er den andre versjonen av patchene, der ytelsesregresjonen og andre problemer oppdaget under testing er fjernet.
