Re: [TEKNIK] Hvorfor bruger denne maskine swap ?



Citat af "Poul Møller Hansen" <sslug@sslug>:

Hej

Jeg undrer mig over hvorfor denne maskine bruger swap space, når der tilsyneladende er rigelig med fri RAM.

$ free
            total       used       free     shared    buffers     cached
Mem:       4058016    1687628    2370388          0     140964     283004
-/+ buffers/cache:    1263660    2794356
Swap:      3951864     569508    3382356

Det kan jo være at der på et tidligere tidspunkt ikke har været rigeligt med ram. Desuden har mange programmer en del kode de kører igennem når de starter, og kun når de starter. Den del kan med fordel swappes ud. I 2.6 kernen findes "swappiness", som er en knap du kan dreje på. Den afgør i hvor høj grad kernen swapper. Du kan bruge denne knap til at justere det.
