Lionel,
It is true that Linux (and most Unix) follow a "full" memory model.
Which means all memory is used for either user programs/libraries or
disk cache.
But I -think- the problem here is that X also uses video memory. And
this extra memory is often reported alongside regular memory,
especially in programs such as top:
Virtual Resource Share
X: 77852 1168 1000
xfs-xtt: 15500 160 160
prime-net: 10580 10240 10240
The first column is -all- memory, main or otherwise. The second is
total real (i.e. main) memory. The last is memory used from the
executable residing in memory; that is both a copy of the executable
and also its libraries.
At least, these interpetations are the best I can manage -- but I'm
sure I'm wrong:
The last example was prime-net, which is small code but allocates
alot to solve a long math problem. So share should not be 10240, but
closer to 240. But xfs-xtt at least makes sense since it should use
mostly video memory to store it's font's.
If you are wondering why my X is so small it is because I am only
running one xterm and a minimal window manager. If, for example I
load mozilla, my memory jumps up to Res:3096.
One last note, I -am- certain about this: Virt >= Res >= Share and
that most of the time Virt ~= Res ~= Share, that is they are, for the
most of time, very close.
Hope that helps,
Gryn
