It does not matter that you installed from CD#1 or by another method
such as DVD or network installation. All are equivalent. What
matters is what you have installed and then what you have started
running.

+1 for htop. Install htop and look at its bar graph visualization.
# apt-get install htop
As my machine is sitting right now with two web browsers open plus
emacs plus dozens of terminals I am consuming 1578M of ram in
userspace processes. The rest of my 4G total ram is used for buffer
cache. I have used 1261M in swap space for pages that I have not
accessed in days and it is better not to have in memory.
I find the biggest consumer of ram pages on my system to be the web
browsers Chromium and Firefox (Iceweasel). The web has gotten to be a
ram hog and when my machine is in need of memory I exit the web
browsers first.
