Oracle tau tshaj tawm qhov hloov tshiab thib ob rau Unbreakable Enterprise Kernel R6, tso rau hauv Oracle Linux faib ua lwm txoj hauv kev rau cov qauv pob nrog cov ntsiav los ntawm Red Hat Enterprise Linux. Lub kernel muaj rau x86_64 thiab ARM64 (aarch64) architectures. Cov hauv paus ntsiab lus, suav nrog kev tawg rau hauv ib tus neeg thaj ua rau thaj, tau tshaj tawm hauv pej xeem Oracle Git repository.
Unbreakable Enterprise Kernel 6 yog raws li Linux 5.4 kernel (UEK R5 yog raws li 4.14 kernel), uas tau hloov kho nrog cov yam ntxwv tshiab, kev ua kom zoo thiab kho, thiab tseem raug sim rau kev sib raug zoo nrog feem ntau cov ntawv thov khiav ntawm RHEL, thiab tshwj xeeb yog optimized. rau kev ua haujlwm nrog kev lag luam software thiab cov cuab yeej Oracle. Kev teeb tsa thiab src pob nrog UEK R6 kernel yog npaj rau Oracle Linux 7.x thiab 8.x.
Cov kev hloov loj:
- Rau cgroups, tus tshiab slab nco maub los tau ntxiv, uas yog qhov tseem ceeb rau kev txav slab accounting los ntawm lub cim xeeb nplooj ntawv mus rau lub kernel khoom theem, uas ua rau nws muaj peev xwm mus qhia slab nplooj ntawv nyob rau hauv txawv cgroups, es tsis txhob faib cais slab caches rau txhua. cgroup. Txoj kev npaj ua kom muaj peev xwm ua kom muaj txiaj ntsig ntawm kev siv slab, txo qhov loj ntawm lub cim xeeb siv rau slab txog li 50%, txo qhov kev nco tag nrho ntawm cov ntsiav thiab txo cov cim xeeb tawg.
- Rau Mellanox ConnectX-6 Dx li, tus tsav tsheb vpda tshiab tau ntxiv nrog kev txhawb nqa rau vDPA (vHost Data Path Acceleration) lub moj khaum, uas tso cai rau koj siv kho vajtse acceleration rau I/O raws li VirtIO hauv virtual machines.
- Kev txhim kho ntsig txog kev txhawb nqa rau NVMe cov cuab yeej tau nqa los ntawm Linux ntsiav 5.9.
- Kev kho thiab txhim kho tau raug xa mus rau Btrfs, CIFS, ext4, NFS, OCFS2 thiab XFS cov ntaub ntawv.
- Hloov kho cov tsav tsheb, suav nrog lpfc 12.8.0.5 (Broadcom Emulex LightPulse Fiber Channel SCSI) nrog kev txhawb nqa rau 256-gigabit hom rau SCSI Fiber Channel, mpt3sas 36.100.00.00 (LSI MPT Fusion SAS 3.0), qla2xxx 0.02.00.103Logic Channel HBA).
- Ntxiv kev sim kev txhawb nqa rau VPN Wireguard, ua tiav ntawm qib kernel.
- NFS tau ntxiv kev sim txhawb nqa rau lub peev xwm los luam cov ntaub ntawv ncaj qha ntawm cov servers, txhais hauv NFS 4.2 specification
- Tus neeg ua haujlwm teem sijhawm muaj peev xwm sim txwv qhov kev ua kom sib luag ntawm cov haujlwm tseem ceeb ntawm CPU cores sib txawv los thaiv cov kab xau cuam tshuam nrog kev siv cov cache sib koom ntawm CPU.
