Game da sabon sigar 2.0
Ofaya daga cikin mafi kyawun fasalulluka na ZFS shine ƙwarewar karatun sa na ci gaba, da aka sani da ARC. ARC Level 2 Persistence (L2ARC) ana aiwatar dashi ta hanyar rubuta metadata lokaci zuwa lokaci zuwa na'urar L2ARC don ba da damar shigar da maƙallan rubutun ta L2ARC a cikin ARC lokacin shigo da ruwa ko kawo na'urar L2ARC akan layi, rage tasirin na tsarin adana lokacin aiki. Saboda haka, ZFS sanannen tsarin fayil ne don dandamali na ajiya.
Tsarukan da ke da manyan saitunan aiki kuma na iya aiwatar da ɗakunan karatu na tushen SSD, wanda ake kira L2ARC, wanda ke cika daga bulolin ARC da ake fitarwa.
A tarihance, ɗayan manyan matsaloli tare da L2ARC shine yayin da tushen SSD ɗin ke dorewa, L2ARC kanta ba haka bane; ba komai a duk lokacin da ka sake yi (ko fitarwa da shigo da shi daga rukuni). Wannan sabon aikin yana bawa bayanan L2ARC damar kasancewa kuma mai yuwuwa tsakanin hawan shigo da shigo da rukuni (gami da sake dawo da tsarin), yana haɓaka ƙimar darajar kayan aikin L2ARC.
Wani sabon abu na wannan sabon sigar na OpenZFS 2.0 shine yayi cikakken línea matsawa, tunda Zstd compressing algorithm (a al'adance mafi yawan algorithm da ake amfani da shi shine lz4) yana ba da matsakaicin matsakaicin matsakaici, amma nauyin CPU mai sauƙin gaske.

Baya ga manyan abubuwan da aka bayyana a sama, OpenZFS 2.0.0 fasali an sake tsara shi da inganta shafukan mutum, har da ya inganta ingantaccen aiki yayin lalata, aikawa da karɓar zfs da ingantaccen sarrafa ƙwaƙwalwar ajiya da ingantaccen aikin ɓoyewa.
