Memory Usage

Hi. I just installed OpenSUSE 10.3 64-bit version.I configured compiz and some other stuff but i noticed that SUSE is eating about 600 mb(no programs running in the background) of my system ram. When i turn compiz it rises to 720 mb. A friend was runing Ubuntu with beryl and he turned off all efects except the cube and his memory usage was max 250mb..300mb with all efects. Why is suse using so much memory? Is it because i use the 64 bit version?

what do you mean "memory usage"?
note that kernel will use all available memory for disk cache and buffers so the normal is to have only a few mb free but cache & buffers memory will be released for applications at any time
menu -> system -> monitor -> ksysteminfo will show you detailed map of memory
if you have 600/720 mb without cache and buffers something is really wrong

This is how it looks

Is this normal on Linux? Is my swap to big? I just dont want Linux to chocke like Windows do.

Nah, you have roughly 2 gigs of swap space, which is fine. Plus, you've got only 51% of memory being used up by applications. The rest is all free, or it's cache, which just makes your frequently-used applications run faster when you start them up. So you've got nothing to worry about. Mine is the same way:



PS: If you want a cool utility to keep track of your disk/memory usage real-time, try gkrellm or one of the widgets for the superkaramba program. Both are really cool but I use gkrellm. It should be listed when you do a search for it in Yast.
