Nika kuqala imiyalo eyenziwe ku-terminal

Wake waphupha usebenzisa umyalo kusuka ku-terminal, ukukhawulela inani le- izinsiza ezabiwe kulokho umyalo? Isixazululo esivezwe lapha singakusiza ukuthi uqhubeke usebenze ngokujwayelekile ngisho nezikhathi ngemuva kokwenza imisebenzi evame ukuba "nzima kakhulu" kuwe. hardware futhi ngokuvamile "balengisa" uhlelo.

Iprosesa (CPU)

Umyalo weNice uvumela ukuguqula okubaluleke kakhulu kwenqubo ngaphezu kwakho konke ngaphakathi kohlelo.

I-Linux kernel iphethe ukuhlela nokubeka isikhathi se-CPU kunqubo ngayinye esebenza ohlelweni. Ububanzi bezabelo ezibekiwe obutholakalayo ngu -20 kuye ku-20, kuthi -20 kube okubaluleke kakhulu futhi okungama-20 kube okuphansi kakhulu.

Ngenxa yeNice singaqinisekisa ukuthi ngezikhathi zokusetshenziswa okuphezulu kwe-CPU izinqubo ezifanele zithola amaphesenti aphezulu kakhulu wazo.

I-syntax yomyalo weNice imi kanjena:

kuhle -n UMYALO

Ngakho-ke, uma sifuna ukwenza inqubo ngokubaluleka kwe-10 sizokwenza okulandelayo:

okuhle -n10 / usr / bin / ukuguqula ifayela.gif file.jpg

I-Hard disk

Ifana neNice yi-ionice, ngomehluko wokuthi lokhu kokugcina kukhawulela ukufinyelela kwi-hard drive.

Isibonelo sokusetshenziswa kwayo kungaba okulandelayo:

ionice -c2 -n7 / usr / bin / convert file.gif file.jpg

-c2 "umzamo ongcono kakhulu", futhi -n7 kuyinto ebaluleke kunazo zonke ngaphakathi "komzamo omuhle kakhulu". Ngale ndlela, lo myalo uzoba nokubekwa okuphansi ngaphakathi kolayini we-I / O (okokufaka / okukhiphayo) kuneminye imisebenzi esebenzayo.

ionice -c3 / usr / bin / convert file.gif file.jpg

-c3 (asikho isidingo sokucacisa ileveli ephambili) kusho ukuthi "ayisebenzi kuphela". Imisebenzi ene -c3 eyabelwe yona izosebenza kuphela lapho idiski ingenzi lutho, okusho ukuthi umsebenzi ngeke ube nomthelela ekwenzeni yonke eminye imisebenzi, kepha kuzothatha isikhathi eside ukuzenza.
