Linus Torvalds je pripravil niz popravkov za podsklop za upravljanje pomnilnika v jedru Linux, ki uvajajo optimizacijo za branje manj\u0161ih blokov podatkov iz strani\u010dnega predpomnilnika brez atomskega spreminjanja \u0161tevca referenc (refcount) v strukturi folio. V besedilu spremembe je navedeno, da so bile spremembe, povezani testi in osnutek pripombe ustvarjeni z AI-assistentom Claude Code pod nadzorom Torvaldsa. Sprememba je dodana v lo\u010deno vejo jedra noref-filemap-read-with-llm in zaenkrat ni jasno, ali bo prenesena v glavno vejo ali gre le za notranji eksperiment.<\/p>\n

Med testiranjem, zahvaljuju\u0107i zakrpama, uspelo je pove\u0107ati propusnost \u010ditanja malih datoteka u konfiguraciji s 8 niti sa 9.9-10.4 na 30-33 miliona operacija u sekundi (pove\u0107anje od 3 puta), s 4 niti \u2014 sa 8.9-11.6 na 25-26 miliona\/sek (pove\u0107anje od 2 puta), dok je kod jednonitne optere\u0107enosti poraslo sa 7.9-8.1 na 8.8-8.9 miliona\/sek. Pove\u0107anje performansi obja\u0161njava se time da u slu\u010daju simultanog pristupa stranom ke\u0161u dolazi do o\u0161trog nadmetanja izme\u0111u niti prilikom pristupa ke\u0161u. Na primer, kada 8 niti poku\u0161ava istovremeno da \u010dita po 16 bajtova podataka, 99.92% vremena se tro\u0161i ne na samo \u010ditanje, ve\u0107 na \u010dekanje pristupa broja\u010du referenci.<\/p>\n

V popravku za zagotovitev pravilnosti podatkov namesto postavljanja posameznih zaklepov, sprememb \u0161tevcev referenc ali vmesnega predpomnjenja se uporablja obvodna re\u0161itev, ki uporablja odlo\u017eeno sprostitev pomnilnika s sinhronizacijo z mehanizmom RCU (Read-Copy-Update). Predlagana metoda v popravku zagotavlja, da stran pomnilnika ne bo fizi\u010dno spro\u0161\u010dena, dokler branjena nit ne zaklju\u010di kopiranja podatkov.
