I just installed lubuntu 12.04 and have been monitoring memory usage with the "top" command and the task manager GUI.
I'm currently seeing 448 MB of physical RAM used with "top".
However, task manager is telling me that 202 MB is in use.
I only have 500 MB total and am seeing decent performance, so I'm wondering if "top" has an issue.
Can anyone explain the difference between "top" and task manager?
Thanks!

top includes cache/buffered to the used memory. While other tools do not. top reports I'm using almost 3.7 GB!! But it also show about 2.6 as cache so I'm realy only using about 1.1 GB. (which is what htop reports) I recommend htop over top. It's just as lightweight and useful as top, but with extra features.
