I've seen a lot of "top" output thrown around on this topic and a bunch of people have touched on this issue, but let me ask this question:
I'm sitting right now in front of my 1gig machine. I have my normal set of apps open: firefox, thunderbird, konsole, etc. How can I tell if I would benefit from additional RAM? What command and what output do I need to pay attention to?

Another indicator is if you see the ammount dedicated to "buffers" and "cached" is small with little free memory.
By way of an example, this is the top output from my desktop machine currently with 2G of ram (and not to much open right now). Mem: 2075524k total, 1695896k used, 379628k free, 520148k buffers Swap: 3148732k total, 128k used, 3148604k free, 519956k cached There is: 379628k free memory 520148k for disk buffers 519956k currently cached for a total of about 1.4G of ram "available if required" without touching swap. The output of free contains the line -/+ buffers/cache: 655904 1419620 The last bit says the same thing, that about 0.6G is currently actually used and that 1.4G is "available". (Note that free defaults to displaying in kilobytes). At least that is my understanding... -- Don -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
