How do I tell if I need more RAM?

My other two computers have as much physical RAM as they can support (1.5GB and 2GB), but my Linux box has only 384MB of its supported 512MB. It's just a headless box running Ubuntu Server that performs various server-type tasks for my family (Apache/MySQL/PHP, print server, Samba file server, remote BitTorrent) as well as Folding@Home (which I've read doesn't benefit much from RAM). Since there's not even a GUI I think the 384MB it has now is probably fine, but I want to be sure.

Is there a command-line command I can use to determine whether or not I need to get more RAM? I've searched Google, but I'm still a little lost.

free -lm will show your RAM and swap usage in MB. The line you're interested in for RAM is the one that starts with "-/+ buffers/cache:". The first column is RAM used by applications running on the system. The second column is the RAM available to applications.


memory, performance, ram
