Google har sl\u00e4ppt patchar med en f\u00f6rb\u00e4ttrad implementation av LRU-mekanismen f\u00f6r Linux. LRU (Least Recently Used) \u2013 \u00e4r en mekanism som g\u00f6r det m\u00f6jligt att sl\u00e4ppa eller byta ut oanv\u00e4nda minnessidor. Enligt Google skapar den nuvarande implementationen av mekanismen f\u00f6r att best\u00e4mma vilka sidor som ska bytas ut en alltf\u00f6r h\u00f6g belastning p\u00e5 CPU:n och fattar ofta d\u00e5liga beslut om vilka sidor som ska bytas ut. <\/p>\n

I experiment som genomf\u00f6rdes av f\u00f6retaget minskade den nya LRU-implementeringen antalet tv\u00e5ngsavslutningar av program p\u00e5 grund av minnesbrist i systemet (OOM kill) med 18 %, och i Chrome OS minskade antalet borttagna flikar i webbl\u00e4saren p\u00e5 grund av otillr\u00e4ckligt minne med 96 %, medan antalet OOM kill i belastade enheter minskade med 59 %. Detta \u00e4r den andra versionen av patcharna, d\u00e4r regressionsprestanda och andra observerade brister under testningen har \u00e5tg\u00e4rdats.
