Adam Williamson from happyassasin.net has a nice article titled Some comparisons between Fedora 13, 15, 17, 19 and 20. Adam works for Red Hat as Fedora QA Community Manager, meaning he knows what he’s taking about:
We can see that the memory used when you simply boot to a console and log in has changed very little all the way back to Fedora 13, released 2010-05-25. We’re doing a fairly good job of keeping our base system from bloating excessively. 19 and 20 are both 30MB worse than 17, but then, 17 was 25MB better than 15.
The same certainly doesn’t hold true for the graphical desktop, though. Just sitting at a mostly-idle desktop with a terminal open, our memory usage has gone from 275MB under the ancien GNOME 2 regime to 300MB with GNOME 3′s ‘fallback mode’ (which was more or less GNOME 2), then rocketed to nearly 400MB, 535MB, and nearly 700MB in subsequent releases. I haven’t yet looked in detail at the changes, but I did take screenshots of ‘top’ ordered by memory usage for each install.
The measurements are done using free command in a gnome-terminal immediately after bootup. GNOME runs in a virtual machine without hardware acceleration, and it ends up using Mesa llvmpipe driver. These are the graphs based on Adam’s measurements:

Most of my software development takes place on a Debian 7 “wheezy” running LXDE. It is stable and provides me with everything I need. I also keep a copy of Fedora on a different partition on my hard disk, the attraction being the latest versions of gcc and glibc. In this article I will take a look at the latest Fedora release.
Usually when installing Linux, my main concern is the RAM memory. In my work I need as much as I can get. One option would be to start with a regular server install, and add X11, LXDE and everything else on top of it. Building such a system from scratch is not exactly difficult. However, today I’m lazy, and I’ll go for a Fedora LXDE Spin install. I will remove after installation everything I don’t need.
The download page is here. The installer still has some problems, for example updating an existing partition tends to get it confused. First boot in the new system I open a terminal and run free command. It uses 220MB of memory, which is not so bad.
The procedure is simple, I look at ps aux output and remove or disable everything I don’t really need.
First one to go is Clipit. It is a clipboard manager that tracks your every key stroke. As you start the system, it tells you politely what it intends to do, and it advises you not to type passwords. I have no idea why would anybody run this on his computer in a post-Snowden world. So, I open a terminal, su and
# yum remove clipit
