Ungayithuthukisa kanjani ukusebenza kwe-Ubuntu ngenxa yeZSwap

Izinyanga ezimbalwa manje, ithuluzi libiziwe I-ZSwap. Leli thuluzi isisiza ukwandisa ukusebenza kohlelo lokusebenza ngokuphatha kangcono inkumbulo nokwenza imemori yokubhangqa igcinwe kwimemori yenqama hhayi kwenye idivayisi.

Leli thuluzi le-kernel liwusizo, ikakhulukazi uma sinekhompyutha enezinsizakusebenza ezimbalwa, eneprosesa ehamba kancane noma ene-hard hard disk, ebangela ukuthi ukusebenza kohlelo lokusebenza kwehle kancane kunokujwayelekile.

Ngaphambi kokusebenzisa nokusebenzisa iZSwap, kufanele siqiniseke ukuthi asiyenzi isebenze. Ezinguqulweni ezindala ze-Ubuntu, ekunikezelweni okususelwe noma kuzinguqulo ze-LTS kungenzeka ukuthi lo msebenzi awusebenzi. Njengamanje ngisebenzisa Ubuntu 17.10 futhi le nguqulo isivele yenziwe yasebenza ngokuzenzakalela. Kepha okuhle kakhulu zihlole ukuthi iyasebenza yini, ngakho-ke, kufanele sibhale kuphela okulandelayo esigungwini:

cat /boot/config-`uname -r` | grep -i zswap

Uma lokhu kubonakala kithi CONFIG_ZSWAP = y, kuzosho ukuthi iyasebenza, uma ibonakala ifana kodwa igcina ngo- «n», kuyosho ukuthi asiyenzi isebenze. Uma singenakho ukuthi kusebenze kufanele sihlele ifayela le-grub. Ukwenza lokhu sivula i-gedit ngemvume yezimpande:

gksu gedit /etc/default/grub

Futhi sifaka umugqa esikhundleni:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Por

GRUB_CMDLINE_LINUX_DEFAULT = "splash silencioso zswap.enabled = 1 zswap.compressor = lz4"

Siyagcina, sivale ifayela bese sibuyekeza i-grub:

sudo update-grub

Manje kufanele sisebenzise elinye ithuluzi elisebenzisa i-ZSwap, i-compressor ye-Lz4. Ukwenza lokhu, kusuka esigungwini esifanayo, sibhala okulandelayo:

sudo su
echo lz4 >> / etc / initramfs-tools / modules
echo lz4_compress >> / etc / initramfs-tools / modules
update-initramfs -u

Siqala kabusha i-pc futhi manje sesizokwazi ukubheka futhi uma sisebenzise i-ZSwap, sisebenzisa umyalo wokuqala esiwusebenzisa esigungwini bese sikhombisa umyalezo kuqala. Kanjalo sizobona ukwanda kokusebenza kweqembu lethu, ukushesha emisebenzini ethile njengokuvula iGimp.
