At Phoronix we are constantly running Linux benchmarks with
quad-core and even octal-core systems with more than enough RAM and all
of the latest and greatest hardware from the chipsets to the graphics
cards. However, with an increasing number of new Linux users trying out
Linux for the first time on their old computers, we have been asked to
conduct some benchmarks using popular desktop Linux distributions on
older hardware. We have done just that as we try out Ubuntu, Xubuntu,
Fedora, Mandriva, and SimplyMEPIS with an old Intel Northwood system."
