PART 1

With Ubuntu, Kubuntu, and Xubuntu each deploying a different desktop environment (GNOME, KDE, and Xfce respectively), how do each of these distributions compare performance-wise? We have taken two systems -- one with dual Intel Clovertown processors and the other an AMD Sempron -- and tested out each of these distributions in some of our commonly used Linux benchmarks to see how the performance truly stacks up. In this article we will be presenting part one of our results.
