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.
Interesting comparison via Phoronix. This is only part one of the results. Get this, test set up one consists of 2 (TWO) Quad Core (4 CORES) Intel Xeon E5320, with 4GB RAM. Nice. Check it out @ Phoronix
