Kumasistimu afana ne-Unix, okuhlanganisa i-Linux, umthwalo wesistimu ukulinganisa komsebenzi wekhompyutha owenziwe yisistimu. Lesi silinganiso siboniswa njengenombolo. Ikhompyutha engenzi lutho ngokuphelele inesilinganiso sokulayisha esingu-0. Inqubo ngayinye esebenzayo noma ukusebenzisa noma ukulinda izinsiza ze-CPU ingeza oku-1 esilinganisweni sokulayisha.
Iyini isilinganiso esivamile somthwalo?
Njengoba sesibonile, umthwalo isistimu engaphansi kwawo ngokuvamile uboniswa njengesilinganiso ngokuhamba kwesikhathi. Ngokuvamile, i-single-core CPU ingaphatha inqubo eyodwa ngesikhathi. Umthwalo ojwayelekile we-1.0 ungasho ukuthi umongo owodwa umatasa u-100% wesikhathi. Uma isilinganiso somthwalo sehlela ku-0.5, i-CPU ibingasebenzi isikhathi esingu-50%.
I-Linux ibala kanjani isilinganiso sokulayisha?
Isilinganiso sokulayisha - isilinganiso somthwalo wesistimu obalwa phakathi nesikhathi esinikeziwe semizuzu engu-1, 5 kanye ne-15.
...
Izinombolo zifundwa ukusuka kwesobunxele kuye kwesokudla, futhi okukhiphayo ngenhla kusho ukuthi:
- isilinganiso sokulayisha ngomzuzu ongu-1 wokugcina ngu-1.98.
- isilinganiso sokulayisha emaminithini angu-5 wokugcina ngu-2.15.
- isilinganiso sokulayisha emaminithini angu-15 wokugcina ngu-2.21.
Yini ebangela ukulayisha okuphezulu kwe-Linux?

Isiphi isilinganiso sokulayisha esiphezulu kakhulu?
“Isidingo Sokubheka” Umthetho Wesithupha: 0.70 Uma isilinganiso somthwalo wakho sihlala singaphezulu kuka-> 0.70, yisikhathi sokuphenya ngaphambi kokuba izinto zibe zimbi kakhulu. Umthetho othi "Lungisa lokhu manje": 1.00. Uma isilinganiso sakho somthwalo sihlala singaphezu kuka-1.00, thola inkinga futhi uyilungise manje.
Ingabe ukusetshenziswa kwe-CPU okungu-100 kubi?
Uma ukusetshenziswa kwe-CPU cishe ku-100%, lokhu kusho ukuthi ikhompuyutha yakho izama ukwenza umsebenzi omningi kunalokho enekhono lawo. Lokhu kuvamise ukuthi KULUNGILE, kodwa kusho ukuthi izinhlelo zingase zehlise ijubane kancane. Amakhompiyutha ajwayele ukusebenzisa cishe u-100% we-CPU lapho enza izinto ezihlanganisa ikhompyutha njengokugijima imidlalo.
Ubala kanjani isilinganiso somthwalo?
Isilinganiso Somthwalo singabhekwa ngezindlela ezintathu ezivamile.
- Ukusebenzisa umyalo we-uptime. Umyalo we-uptime ungenye yezindlela ezivame kakhulu zokuhlola Isilinganiso Somthwalo wesistimu yakho. …
- Ukusebenzisa umyalo ophezulu. Enye indlela yokuqapha Isilinganiso Somthwalo ohlelweni lwakho ukusebenzisa umyalo ophezulu ku-Linux. …
- Ukusebenzisa ithuluzi lokubuka.
Mangaki ama-cores enginawo e-Linux?
Ungasebenzisa owodwa wale miyalo elandelayo ukuthola inombolo ye-CPU cores ehlanganisa wonke ama-cores ku-Linux: umyalo we-lscpu. ikati /proc/cpuinfo. umyalo ophezulu noma we-htop.
Ngilibona kanjani iphesenti le-CPU ku-Linux?
Ingabe isamba sokusetshenziswa kwe-CPU sibalwa kanjani kumonitha weseva ye-Linux?
- Ukusetshenziswa kwe-CPU kubalwa kusetshenziswa umyalo 'ophezulu'. Ukusetshenziswa kwe-CPU = 100 - isikhathi sokungenzi lutho. Isb:
- inani elingasebenzi = 93.1. Ukusetshenziswa kwe-CPU = ( 100 – 93.1 ) = 6.9%
- Uma iseva iyisibonelo se-AWS, ukusetshenziswa kwe-CPU kubalwa kusetshenziswa ifomula: Ukusetshenziswa kwe-CPU = 100 – idle_time – steal_time.
Ngingakhiqiza kanjani i-CPU ephezulu ku-Linux?
