Yep, you can see your swap usage is zero, additionally you can tweak your vm.swappiness sysctl setting. I usually drop mine down to 10 to reduce its preference of using swap on my laptop and servers when I know my RAM capacity will be sufficient for normal operations.

Look at the *second* line - you only have 228MB of RAM actually being used "for real" - the rest is just cache. The Linux kernel is designed to make use of all available memory for performance reasons, so it will keep loading things as caches until it runs out of stuff to load or RAM to fill. The second line tells you how much is in use disregarding those caches. > Here is the output from ps aux. It looks like java is out of control. Is > this normal? Yes, Java has a reputation for being a resource hog. - Tony _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota tclug-list at mn-linux.org http://mailman.mn-linux.org/mailman/listinfo/tclug-list
