From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The most important parts are at the end of the CPU and GPU performance sections. They performed the same across all desktops. On most modern systems the desktop you use is not going to have any significant impact on your performance, when software you're running requires resources, they will be directed towards it.

Also, low RAM usage is massively overrated, especially by Linux users. Your RAM is there to be used, leaving it unused is a waste. It is good for your desktop to be caching a lot of data in RAM when it is otherwise unused. It's only an issue if its still utilizing an excessive amount of RAM when other apps need it more.

This is actual RAM used by the desktop environments that is not available for cache. That is the number he gets from top, it doesn't include the disk cache. The DE won't use less RAM even when Firefox needs it, because it is not cache, it cannot be dropped if needed, you just have less RAM available for you applications (or for the actual cache, for that matter).
