Linus Torvalds on valmistanud hulga plaastritest, mis kuuluvad Linuxi tuuma m\u00e4lu haldamise alams\u00fcsteemi, et optimeerida v\u00e4ikeste andmeplokkide lugemist lehek\u00fcljekettast ilma viidete arvu (refcount) aatomse muutmiseta folio struktuuris. Commit'i tekstis on m\u00e4rgitud, et muudatustega seotud testid ja m\u00e4rkmed on koostatud AI-assistendi Claude Code poolt Torvaldsi j\u00e4relevalve all. Muudatus on lisatud eraldi tuuma haru noref-filemap-read-with-llm ning hetkel pole selge, kas see kantakse p\u00f5hiharusse v\u00f5i on see lihtsalt sisene katse.<\/p>\n

Testimise k\u00e4igus \u00f5nnestus t\u00e4nu plaastritele suurendada v\u00e4ikeste failide lugemisv\u00f5imet konfiguratsioonis 8 l\u00f5imega 9,9-10,4 miljonilt 30-33 miljonile operatsioonile sekundis (kasv 3 korda), 4 l\u00f5imega 8,9-11,6 miljonilt 25-26 miljonile sekundi jooksul (kasv 2 korda), ning \u00fche l\u00f5ime koormuse korral 7,9-8,1 miljonilt 8,8-8,9 miljonile sekundi jooksul. Tulemuslikkuse kasv on seletatav sellega, et samaaegse juurdep\u00e4\u00e4su t\u00f5ttu lehek\u00fcljel asuvale vahem\u00e4lule tekib l\u00f5imede vahel tugeva konkurentsi t\u00f5ttu ligip\u00e4\u00e4sul viivitusi. N\u00e4iteks, kui 8 l\u00f5ime \u00fcritavad samaaegselt lugeda 16 baiti andmeid, kulub 99,92% ajast mitte lugemisele, vaid ligip\u00e4\u00e4sukirjeldaja ootamisele.<\/p>\n

Plaastris andmete \u00f5igsuse tagamiseks kasutatakse eraldi lukustuste seadmise, viidete arvu muutmise v\u00f5i vahem\u00e4lude rakendamise asemel \u00fcmbers\u00f5idung, mis rakendab edasi l\u00fckatud m\u00e4lu vabastamist RCU (Read-Copy-Update) mehhanismi abil s\u00fcnkroniseerimisega. Pakutud meetod tagab, et m\u00e4lu lehek\u00fclge ei vabastata f\u00fc\u00fcsiliselt, enne kui lugemisprotsess on andmete kopeerimise l\u00f5petanud.
