A Memory Comparison of Light Linux Desktops – Part 3

l3net - a layer 3 networking blog

Linux kernel manages all RAM memory in your computer. Unused memory goes into a special buffering pool, where the kernel caches all recently used data. If a process attempts to read a file and the kernel already has the file cached, reading it is as fast as reading RAM.

Filesystem-heavy task, such as compiling source code, processing video files, etc. benefit from as much free memory as possible in buffering pool. It is not uncommon today to see users with powerful systems running tiling window managers in only a few megabytes of memory. Also, with the personal computer market in decline, people tend to keep their computers longer.

In this article I continue the measurements started in part 1 and part 2 of this series.

I use free command to measure memory. It basically prints out values provided by the kernel. Of interest to us is the number on -/+…

A Memory Comparison of Light Linux Desktops – Part 2

l3net - a layer 3 networking blog

In my previous article I’ve tried to investigate the RAM memory requirements for running some of the most common light window managers and desktop environments available in the Linux world. Prompted by several readers, I’ve decided to include also the big, well-known memory hogs that grab most of the Linux market, i.e. KDE, Unity and Gnome.

I am using the same setup, based on virtenv. It includes its own xserver (Xephyr) and a virtualization container (LXC). The computer is an older 64-bit machine, running Ubuntu 12.04 with LXDE as desktop environment.

A Memory Comparison of Light Linux Desktops

After I install a new version of Linux, I usually take a good look at the screen. Does it have a task bar? Can I find my window after it was minimized? The direction some desktops are going is not clear. Making it easier for current users or for the people coming from Windows or Mac is not a goal anymore. User complains are dismissed, chalking it up to the fact that people don’t like change.

Fortunately, in Linux we have plenty of other choices, and we do like change. We have no need to keep using desktops we don’t like.

I will describe some of choices in this article, and I’ll attempt to measure the RAM memory requirements. I use free command in an xterm before and after the graphic environment is started on a separate X server (Xephyr). free command prints on the screen data made…

My confession

So I walk into a supermarket to get something to drink.  When something wonderful catches my eye. 

No silly not that.

I’m talking about Gelato.  Raspberries and Cream to be more specific.  Anyway I decide to try it because it sounded like something new.

I tasted it and it was indeed delicious so delicious I thought to myself…….

Am I dreamin’?

Then I notice that it tastes mighty familiar.  I decide to look it up to see what it was and surprise…..

Gelato is italian for ice cream!

I thought to myself, “seriously”? For it was a serious “duh” moment.  So I just had to write about it. 

You know what makes this worse?  I am lactose intolerant.  So I am hoping that the Empire will not in fact strike back.

Good grief!
