First question is, does the computer have enough memory for what it's doing? If there's enough memory for everyone, there's no need to worry, but if the computer is low on memory, sort the process list by 'Real memory' to see who's using the most. Often quitting an application and restarting it will make it use less memory. (Firefox and OpenOffice are particularly good examples of this)
The pie chart shows how the memory in the machine is being used. In this picture, it looks like I don't have a lot of memory "free" (that tiny little green slice), but that's not something to worry about.
The important slice to look at is the blue "Inactive" slice. Ideally, you want the blue and green (inactive & free) to be as large a fraction as possible of your memory. At least a quarter, as a rough rule of thumb.
In this image, VirtualBox is hogging up most of my memory (but that's okay -- I'm running Linux in there) but despite that I still have ~700Mb of inactive memory -- this means that all the processes that NEED active memory already have enough. So my machine is still really snappy.

Isn't this fun? A Mac utility called GrandPerspective maps out the contents of my hard drive - lots of snazzy colourways, this one is 'Olive sunset'!!

Move mouse to the right top corner, Compiz-Fusion scales all the Windows to show a bird-eye view
The right lower corner is Windows Vista running in VirtualBox.
I installed VirtualBox in Ubuntu 9.10 Karmic Koala. Because My ThinkPad only installed Ubuntu but use Windows only ActiveX in Korea's Web Environment. posted by 똘똘한성군
Panflute (primero de la izquierda) es un applet, es decir, un agregado para el panel de GNOME (que es el "Entorno de Escritorio" de Ubuntu. Sirve para escuchar música, calificarla, avanzar y retroceder, y te informa de los nombres. Todo cofigurable. Se ubica donde vos quieras. :-)
A su derecha, los cuatro escritorios virtuales que vienen predeterminados. Se pueden agregar más o dejar un par. A gusto del usuario. Puede verse que en el primero está corriendo Firefox con varias pestañas abiertas, en el segundo está el Thunderbird y una planilla en Calc, en el tercero VirtualBox con Windows XP, y en el cuarto está Wuala, un cliente de almacenamiento social (especie de P2P) y el rectangulito es el cliente de BitTorrent Transmission. Esos son los programas o ventanas que se ven, porque están en primer plano, pero hay otros más corriendo simultáneamente. Mi máquina es un Athlon 64 X2 5000+ y 2 GB de RAM, que compré hace un par de años. :-)
A la extrema derecha, una flechita indica que el panel se puede correr para tener más espacio vertical en la pantalla. Muy útil en una notebook o netbook.
Ubuntu 10.10 para todo público
