Memory and swap usage

[courcol]

Hello,

Is there someone to tell me why:
$ lsps -a
Esp.pag. Vol. physique Groupe de vol. Taille %Utilisé Actif Auto Type
hd6 hdisk0 rootvg 2048Mo 18 oui oui lv

while:
$ svmon -F
Processing.. 100%
percentage of memory used: 41,60%

The first one let me think I should add memory on my server. On the other hand, if only 41% of memory is really in use, why is Aix using 18% of swap space ?

Using *some* paging space isn't necessarily a bad thing. Have a look at:
