Siphi indawo yokutshintsha kwiLinux?

Ukutshintshana sisithuba esikwidiski esisetyenziswa xa ubungakanani benkumbulo ye-RAM ebonakalayo igcwele. Xa isixokelelwano se-Linux siphelelwa yi-RAM, amaphepha angasebenziyo ayasuswa kwi-RAM ukuya kwindawo yokutshintsha. Indawo yokutshintsha ingathatha imo nokuba yeyahlulelo ezinikeleyo yokutshintsha okanye ifayile yokutshintsha.

How Big Should Linux swap partition be?

That should usually be more than enough swap space, too. If you have a large amount of RAM — 16 GB or so — and you don’t need hibernate but do need disk space, you could probably get away with a small 2 GB swap partition. Again, it really depends on how much memory your computer will actually use.

How much memory does Linux swap use?
