¿Komputa yako haina ndangariro zhinji inowanikwa? Ukangotanga kuvhura mapurogiramu mazhinji zvinotanga kushanda verenga? Zvakanaka, iyi haisi mhinduro (pamwe unofanirwa kufunga nezvekushandisa lighter distro kana, kana zvichibvira, kukwidziridza komputa yako) asi inogona kukubatsira. bvisa yako system cache. Nokusingaperi, Linux inokura cache kusvika yashandisa zvese zviripo ndangariro. Izvi zvakajairika, masisitimu ese anoshanda anoita kuti akurumidze kumhanya kwazvo. Dambudziko nderekuti dzimwe nguva izvi zvinogona kuburitsa zvinokonzeresa: kunonoka, kupenya muvhidhiyo, nezvimwe. |
Chii chinonzi cache?
Iyo cache ndeye diki uye nekukurumidza ndangariro, iyo inochengeta makopi eiyo data iri mune huru ndangariro inoshandiswa kazhinji kazhinji.
Icho chikamu che duplicate data kubva kune mamwe mavambo, ine chivakwa icho data rekutanga rinodhura kuwana, kazhinji munguva, zvichienzaniswa nekopi iri mu cache. Kana data ikawanikwa kekutanga, kopi inoitwa mune cache; anotevera mapindiro anoitwa kune akati kopi, zvichideredza avhareji yekuwana nguva kune data.
Kana processor ichida kuverenga kana kunyorera kune imwe nzvimbo mundangariro huru, inotanga yaongorora kuti uone kana kopi yedata iri mune cache. Kana zvirizvo, processor ipapo inoverenga kana kunyorera cache, iyo inokurumidza kupfuura kuverenga kana kunyora kune chikuru memory.
Ndingajekese sei zviri mune cache?
sudo su sync && echo 3> / proc / sys / vm / drop_caches kubuda
En GNOME iwe unozogona kuona mhedzisiro yemurairo uyu zvakanyatsojeka kana iwe ukawedzera iyo System Monitor kune iyo pani.

Ini handina kuwana iyo drop_caches chinhu, asi zano nderekuti iwo ekudzora mafaera; iyo 3 ingave iri yekuraira kuburitsa cache. Ini ndinofungidzira kana yadururwa inodzokera ku0 iyo faira. Chokwadi inodzokera ku0 kana iwe ukatangazve, imwe yacho haitarise
Ndinokutendai!

Uye ne

o
rm /proc/sys/vm/drop_caches/.*
Hazvishande zvakafanana here?
Edza ... asi handifunge kudaro.
Kwaziwai!
izvo munyori wepositi anoisa kwazvo !! anoshanda !! iyo yekuchinja?

Nemutemo wekubvumirana unodzivirira kudzima zvinhu kubva mundangariro yeSRAM iri kushanda.
Maitiro 0 kusvika ku3 anoudza kernel zvinhu zvaunoda kusunungura kubva kuSRAM.

Indes metadata uye dentries dhairekitori info hukama hwemafaira arimo ... mira sezvizvi, pakati pekugadzirisa piritsi uye yangu yekare ndangariro ...
iwe unogona kugadzira bhatani mumenu ine sh faira rekubvumirana; echo 3> / proc / blablabla donhedza-caches (Ndine chokwadi kuti mukomana akanaka akazvitumira)

Zvakanaka ndakazviedza, ndakavhura yangu drop_caches faira kuti ndione zvayainayo uye yakangoisa 0, kushandisa
kubvumirana && echo 3> / proc / sys / vm / drop_caches
Zvemukati zvayichinja kubva pa0 kuenda pa3, izvo zvingave zvakasiyana zvakanyanya nekushandisa rm nekuti izvo zvaizodzima iyo faira zvachose.
Kunyangwe ini ndisiri kunzwisisa kuti zvinokanganisa sei kuva nezviri mukati uye zvinoshandurwa kuita 0.
