I have an IBM ThinkCentre, model M1. I just upgraded from 2.5 to 4 gigs of memory.
I am running Kubuntu 8.04 Linux on my desktop. When I run th free command, I get the following:
$ free -m
total used free shared buffers cached
Mem: 2534 2461 72 0 20 843
-/+ buffers/cache: 1598 935
Swap: 3820 1105 2714
It is showing only 2.5g memory but 1.5g in cache.
Is this normal? When I run free on my Centos server with 12g of memory, I have all 11.5g in memory and only .5g in cache.
Is there a way to change this? Should I?
BTW--I've checked the bios settings and don't see anything obvious to change.
