Power & Memory Usage Of GNOME, KDE, LXDE & Xfce

Filed under
KDE
Software

Xfce, LXDE, and other desktop environments are often referenced as being lighter-eight Linux desktop environments than KDE and GNOME, but what are the measurable performance differences between them? Curious how much of a quantitative impact the GNOME, KDE, Xfce, and LXDE desktops have on netbook systems, we carried out a small set of tests to look at the differences in memory usage, battery power consumption, and thermal performance.

While the Phoronix Test Suite is most often used by us and others to carry out direct performance benchmarks or other tests using the different test suites and profiles, the open-source testing platform of ours also has an advanced sensor monitoring framework with logging capabilities. The Phoronix Test Suite through the underlying Phodevi (Phoronix Device Interface) library is able to monitor various system vitals ranging from hardware sensors like the CPU temperature, system temperature, and battery power consumption to software values like the CPU and GPU utilization, IOwait, disk read/write speeds, and memory usage.

We installed each of the tested desktop environments through the Ubuntu Lucid repository and they included GNOME 2.29.91, KDE SC 4.4.1, LXDE 0.5, and Xfce 4.6.1.

How to set up Raspberry Pi, the little computer you can cook into DIY tech projects

You don't need an electrical engineering degree to build a robot army. With the $35 Raspberry Pi B+, you can create robots and connected devices on the cheap, with little more than an Internet connection and a bunch of spare time. The Raspberry Pi is a computer about the size of a credit card. The darling of the do-it-yourself electronics crowd, the Pi was originally designed to teach kids computer and programming skills without the need for expensive computer labs. People have used Raspberry Pis for everything from robots to cheap home media centers. The Pi sports USB ports, HDMI video, and a host of other peripherals. The latest version, the B+, sports 512MB of RAM and uses a MicroSD card instead of a full-size card. Read more

LibreOffice Ported To 64-bit ARM (AArch64)

As more and more open-source programs get brought up for 64-bit ARM, LibreOffice is the latest to receive such AArch64 enablement. As of today in LibreOffice Git is the initial AArch64 support. Over one thousand new lines of code were added to LibreOffice by Red Hat's Stephan Bergmann for allowing the open-source office suite to build on the ARMv8 64-bit architecture. LibreOffice already runs on many CPU architectures from x86 to Alpha and SPARC with ARM64 just being the latest. Read more

SUSE's Flavio Castelli on Docker's Rise Among Linux Distros

Docker has only gained traction since its launch a little over a year ago as more companies join the community's efforts on a regular basis. On July 30, the first official Docker build for openSUSE was released, making this distribution the latest among many to join the fray. I connected with Flavio Castelli, a senior software engineer at SUSE, who works extensively on SUSE Linux Enterprise and has played a major role in bringing official Docker support to openSUSE. In this interview, he discuses the importance of bringing Docker to each Linux distribution, the future of Docker on SUSE Linux Enterprise, and other interesting developments in the Docker ecosystem.
