Uhla lwemibhalo ye-athikili
Uma ikhompyutha yakho (ikhompyutha) ihamba kancane, ungase ufune ukuhlola ukuthi uhlelo lungaphansi komthwalo omkhulu?
Muva nje, umakethi wedijithali uthe iwebhusayithi ye-e-commerce ayiphathayo ibhekane nezinkinga futhi ayizange itholakale isikhathi esithile…
Iwebhusayithi yakhiwe kusetshenziswa i-WordPress futhi ibanjwe kuseva ye-Linux VPS.
- Ukucushwa kweseva ye-Linux VPS kunomongo we-CPU ongu-1 kuphela kanye nenkumbulo ye-RAM engu-1GB.
Ngena ngemvume kusizinda seseva ye-Linux VPS ukuze uhlole inkinga, futhi uthole ukuthi isilinganiso somthwalo siphezulu kakhulu, sifinyelela ngaphezu kwe-10.0.
Kuzinhlelo ze-Linux, sivame ukusebenzisauptimeumyalo wokuyibuka (wumyalo futhitopumyalo uyatholakala).
Ukwengeza, baphinde basebenze namakhompyutha we-Apple Mac.
Uma uthola ukuthi isilinganiso somthwalo siphezulu kakhulu, zama ukuxazulula inkinga!
- Uma isilinganiso somthwalo somthwalo siphezulu kakhulu,U-Chen WeiliangIsixazululo esinikezwe ukukhulisa inani lama-CPU cores.
- Bese, thuthukisa ngokuqiniseka ukucushwa kokuthi2 CPU cores,8 GB Inkumbulo ye-RAM,
- Isimo sokulayisha esimaphakathi esiphezulu saxazululwa ngokushesha.
XNUMX. Hlola umthwalo wesistimu
Ewindini letheminali ye-SSH, thayipha umyalo olandelayo▼
uptime
Uhlelo luzobuyisela ulayini wolwazi ▼
Ingxenye yesibili yomugqa ithi "isilinganiso somthwalo" okusho ukuthi "isilinganiso somthwalo wesistimu"
- Ngezinombolo ezingu-3 ngaphakathi, singakwazi yini ukunquma ukuthi umthwalo wesistimu mkhulu noma mncane?
Kungani kunezinombolo ezi-3?
- Zimelela isilinganiso somthwalo wesistimu ngemizuzu engu-1 iminithi, imizuzu emi-5 nemizuzu eyi-15.
- Uma uqhubeka nokubheka, kuzokutshela nokuthi uma i-CPU ingasebenzi ngokuphelele, isilinganiso somthwalo singu-0;
- Uma umthwalo womsebenzi we-CPU ugcwele, isilinganiso somthwalo singu-1.
Isho ukuthini i-CPU?
- I-CPU iyunithi yokucubungula emaphakathi.
- (I-English Central Processing Unit, CPU)
- I-CPU iwumongo wekhompuyutha nomongo wokulawula wekhompyutha.
Ukusetshenziswa kwe-CPU
- Ukusetshenziswa kwe-CPU ulwazi lwezibalo lwesimo sokusetshenziswa kwe-CPU esikhathini esithile.
- Lesi sikhombi sibonisa ukusetshenziswa kwe-CPU (lapho i-CPU isebenza).
- Uma i-CPU imatasa isikhathi eside, udinga ukucabangela ukuthi ingabe i-CPU igcwele kakhulu. ?
- Ukusebenza kokugcwala ngokweqile isikhathi eside kuwuhlobo lomonakalo emshinini ngokwawo.
- Ngakho-ke, ukusetshenziswa kwe-CPU kufanele kulawulwe ngokwesilinganiso esithile ukuze kuqinisekiswe ukusebenza okuvamile komshini.
Yini Isilinganiso Somthwalo?
- Isilinganiso sokulayisha umthwalo we-CPU, futhi ulwazi oluqukethe izibalo zesimo sokusetshenziswa kwe-CPU ngaphakathi kwesegimenti.
- Izibalo zesamba sokucutshungulwa kwe-CPU kanye nenani lezinqubo ezilinde ukucutshungulwa kwe-CPU isikhathi esithile.
- Okusho ukuthi, izibalo zobude bomugqa ezisetshenziswa yi-CPU.
Ngokusobala, inani eliphansi "lesilinganiso somthwalo", njengokuthi 0.2 noma 0.3, kusho ukuthi umthwalo wekhompyutha (ikhompyutha) uncane futhi umthwalo wesistimu ulula.
- Nokho, ungabona nini ukuthi uhlelo lungaphansi komthwalo osindayo?
- Ekugcineni ilingana nehora elingu-1?Noma ingabe ilingana no-0.5?Noma ilingana no-1.5?
- Yini okufanele ngiyenze uma la manani amathathu ehlukile phakathi nomzuzu ongu-1, imizuzu emi-5 nemizuzu eyi-15?
XNUMX. Isifaniso
Ukuze unqume ukuthi isistimu yakho igcwele kakhulu yini, kufanele uqonde ukuthi isilinganiso somthwalo sisho ukuthini ngempela.
Okulandelayo, uChen Weiliang uzochaza lolu daba ngolimi olulula noluqondakala kalula.
Okokuqala, sicabanga ukuthi esimweni esilula, ikhompuyutha yakho ine-CPU eyodwa kuphela, futhi yonke imisebenzi kufanele yenziwe yile CPU.
Ake sicabange ngomthwalo omaphakathi wale CPU njengebhuloho:
Munye kuphela umzila ebhulohweni futhi zonke izimoto kufanele ziwele lo mzila.
(Ngokusobala, ibhuloho lingasetshenziswa ohlangothini olulodwa kuphela.)
Uma umthwalo wesistimu ungu-0, kusho ukuthi ayikho imoto ebhulohweni ▼
Umthwalo wesistimu ungu-0.5, okusho ukuthi kukhona uhhafu wezimoto ebhulohweni ▼
Umthwalo wesistimu ungu-1.0, okusho ukuthi kunezimoto kuzo zonke izingxenye zebhuloho, okusho ukuthi ibhuloho "ligcwele" ▼
- Kodwa kufanele kuphawulwe ukuthi ibhuloho lisengadlula kahle lapha.
Umthwalo wesistimu ungu-1.7, okusho ukuthi izimoto ziningi futhi ibhuloho ligcwele (100%).
- Izimoto ezilinde ebhulohweni zibalelwa ku-70% wezimoto zasebhulohweni.
Ngokufanisa, nokunye, umthwalo wesistimu ngu-2.0:
- Okusho ukuthi kunezimoto eziningi ezilindile njengoba kunezitezi zamabhuloho.
- Ukulayisha kwesistimu okungu-3.0 kusho ukuthi kunezimoto eziphindwe kabili ebhulohweni kunedekhi.
- Uma umthwalo wesistimu ungaphezu kuka-1, imoto yangemuva kufanele ilinde;
- Uma uhlelo lulayisha, kuba side isikhathi sokulinda sokuwela ibhuloho▼
- Umthwalo wesistimu we-CPU ngokuyisisekelo ulingana nomthamo webhuloho le-analogi elishiwo ngenhla, okungumthwalo omkhulu womsebenzi we-CPU.
- Imoto esebhulohweni iyinqubo elinde i-CPU ukuthi icutshungulwe.
Uma i-CPU icubungula ubuningi bezinqubo eziyi-100 ngomzuzu, umthwalo wesistimu ngu-0.2, okusho ukuthi i-CPU icubungula izinqubo ezingu-1 kuphela kulo mzuzu ongu-20;
Umthwalo wesistimu ongu-1.0 usho ukuthi i-CPU iphatha izinqubo eziyi-1 kulo mzuzu ongu-100;
1.7 Lokhu kusho ukuthi ngaphezu kwezinqubo eziyi-100 i-CPU ezicubungulayo, kunezinqubo ezingu-70 ezilindele ukucutshungulwa yi-CPU.
Ukuze usebenzise ikhompuyutha kahle, umthwalo wesistimu akufanele udlule u-1.0, ngakho-ke asikho isidingo sokulinda noma iyiphi inqubo futhi zonke izinqubo zingacutshungulwa kuqala.
Ngokusobala, i-1.0 iyinani eliyinhloko.
Uma leli nani leqiwe, isistimu ayilungile.Kumele ungenelele.
XNUMX. Isilinganiso sokulayishwa kwesistimu sifanelekile kangakanani?
Ingabe u-1.0 uyivelu efanelekile yokulayisha kwesistimu?
Akunjalo, ama-sysadmins avame ukushiya isikhala esincane.
Uma leli nani lifinyelela ku-0.7, kufanele wazi okuthile okufana nalokhu:
- Uma umthwalo wesistimu uqhubeka uba mkhulu kuno-0.7, kufanele uqale ukuphenya inkinga futhi uvimbele isimo ukuthi singabi sibi kakhulu.
- Uma umthwalo wesistimu uqhubeka uba mkhulu kuno-1.0, kufanele uthole isixazululo futhi wehlise inani.
- Uma umthwalo wesistimu ufinyelela ku-5.0, kubonisa ukuthi kunenkinga enkulu ngohlelo, futhi aluphenduli isikhathi eside, noma cishe ukuphahlazeka.Akufanele uvumele isistimu ifinyelele leli nani.
Amaphrosesa amane, ama-CPU amaningi
Okungenhla kucabanga ukuthi ikhompuyutha yakho (ikhompyutha) ine-CPU eyodwa kuphela.
Kwenzekani uma ikhompuyutha yakho (ikhompyutha) inama-CPU angu-2 afakiwe?
2 CPUs kusho ukuthi amandla okucubungula ekhompyutha (ikhompyutha) aphindwe kabili, futhi inani lezinqubo ezingacutshungulwa ngesikhathi esifanayo liphindwe kabili.
UChen Weiliang uyaqhubeka nokusebenzisa isifaniso sebhuloho lapha; ama-CPU amabili asho ukuthi ibhuloho lineziteshi ezimbili, okwandisa kabili umthamo wethrafikhi.
- Ngakho-ke, ama-CPU angu-2 asho ukuthi umthwalo wesistimu ungafinyelela ku-2.0, futhi i-CPU ngayinye ifinyelela umthwalo womsebenzi ongu-100%.
- Kukhompyutha enama-CPU angu-n.0, umthwalo wesistimu owamukelekayo ungafika kuma-CPU angu-n.0.
Ezinhlanu, i-multi-core CPU processor
Abahlinzeki be-chip ngokuvamile baqukatha ama-CPU cores amaningi ngaphakathi kwe-CPU engu-1, ebizwa ngokuthi "i-multi-core CPU".
I-multi-core CPU ifana ne-multi-CPU ngokomthwalo wesistimu.
Ngakho-ke, uma ucabangela umthwalo wesistimu, kufanele ucabangele ukuthi mangaki ama-CPU ikhompuyutha yakho?Futhi bangaki ama-cores CPU ngayinye inawo?
Khona-ke, ngokuhlukanisa umthwalo wesistimu ngenani eliphelele lama-cores, inqobo nje uma umthwalo ngomgogodla ngamunye ungadluli u-1.0, ikhompuyutha izosebenza njengokujwayelekile.
Wazi kanjani ukuthi mangaki ama-CPU cores ikhompuyutha enawo?
Ngokusebenzisa umyalo, ikuvumela ukuthi ubuke imininingwane ye-CPU ▼
cat /proc/cpuinfo
Imiyalo ebuyisela ngokuqondile ingqikithi yenani lama-cores we-CPU▼
grep -c 'model name' /proc/cpuinfo
XNUMX. Isiphi isikhathi esimaphakathi somthwalo okufanele ngibheke?
umbuzo wokugcina:
Isilinganiso sokulayisha "isilinganiso somthwalo" sibuyisela isamba sezilinganiso ezintathu:
- Umthwalo wesistimu weminithi elingu-1, umthwalo wesistimu wamaminithi angu-5, umthwalo wesistimu wamaminithi angu-15.
Iliphi inani okufanele ngibhekisele kulo?
- Uma umthwalo wesistimu ungaphezu kuka-1 ngomzuzu ongu-1.0 kuphela, ezinye izikhathi ezingu-2 zingaphansi kuka-1.0, okubonisa ukuthi lokhu kuyinto yesikhashana kuphela futhi inkinga ayibucayi.
- Uma isilinganiso somthwalo wesistimu mkhulu kuno-15 phakathi kwemizuzu engu-1.0 (ngemuva kokwandisa inani lama-CPU cores), inkinga isekhona, hhayi into yesikhashana.
- Ngakho-ke, kufanele uqaphele ikakhulukazi "umthwalo wesistimu wemizuzu engu-15" njengenkomba yokuthi ikhompuyutha (ikhompyutha) isebenza ngokujwayelekile.
Okulandelayo kumayelana nomyalo ophezulu/ukusetshenziswa kwe-CPU/ukulayisha okumaphakathi kwendlela yokubala ▼
Yini okufanele ngiyenze uma umthwalo we-VPS uphezulu kakhulu?
Manje iwebhusayithi yami ayikwazi ukufinyelelwa ngoba umthwalo uphezulu kakhulu, yini okufanele ngiyenze?
phezulu – 20:44:30 phezulu 12 min, umsebenzisi ongu-1, isilinganiso sokulayisha: 2.21, 8.39, 6.48
- Iseva yakho iyazilawula, okufanele ngabe uyayenza ukuhlola iseva yakho ngokwayo nge-SSH.
- Hlola ukuthi isebenza ngani?Iyiphi inqubo nokunye?
- Uma kunesidingo, zama ukuqalisa kabusha iseva.
- Uma ngemva kokuqalisa kabusha iseva, umthwalo usephezulu kakhulu, zama ukuhlonza inqubo elayishwe kakhulu futhi uyimise.
- Uma kunesidingo, qala kabusha inqubo (hhayi iseva) ngayodwana.
- Noma ngemva kokubonisana nenkonzo yamakhasimende "kungani umthwalo we-VPS / iseva uphezulu kakhulu", akusekho indlela yokwenza, futhi ekugcineni indlela kuphela yokwandisa ukucushwa kweseva.
Yisiphi isayizi esifanele sokubamba iwebhusayithi yenkampani yokuhweba kwamanye amazwe?
Ungakhetha kanjani ukucushwa kweseva okulungile?Chofoza isixhumanisi esingezansi ukuze ubuke isilinganiso sansuku zonke sesixazululo seseva ye-IP engu-1 ▼
Ngethemba ukuthi isihloko esithi "Isilinganiso Somthwalo We-Linux Kufanele Sibe Siphezulu Kangakanani? Ukuhlolwa Kokusetshenziswa Komthwalo We-CPU" esabiwe kubhulogi likaChen Weiliang ( https://www.chenweiliang.com/ ) sizokusiza.
