Swap question.

[destroyedlolo]

Hello,

My main system is an old Athlon 1.1 Ghz with 1.5 Go of RAM.

I installed LXDE on it, and mainly using Firefox, Gimp, Kino, Avidemux2, LibreOffice and obviously some C(++) compilation. In background, I have a website (Apache, PostgreSQL and PHP5) for development purposes.

All in all, my memory usage is b/w 20-30% in general and I never see Conky's RAM usage above 50%.

Currently, my figures are :

• RAM usage : 320M (21%)
  
• Buffers : 119 M
  
• Cache : 1.01 G
  

But, why I have also 24 Mo used in my swap ?

Thanks

Laurent

AFAIK you should set some low value for vm.swappiness in your /etc/sysctl.conf
Try setting this value in console with

You should be glad it's swapping. Idle stuff in RAM (getty is an obvious culprit) is just taking up space that could be used for something better, like caching hard drive writes, or pre-fetching, or running programs. Linux is trying to be your friend and do what's best for you, ie put as much of your system to as good of a use as possible.

Addendum: I know this ain't FreeBSD, but http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/misc.html#MORE-SWAP

Hi all,

Sorry for this late response : I had problem with my system and then forgot this issue ... until now I'm editing video with cinelerra and I can see the swap increasing even if only 40% of the memory is used (but cache/buffer obviously ).
