Last week we looked at the Ubuntu 9.10 netbook performance with two Atom-powered netbooks comparing the Karmic Koala numbers against that of Ubuntu 9.04. For the most part, Ubuntu 9.10 offered better performance over its predecessor, but there were a few performance drops in different areas. With our netbook results out of the way, next up we looked at how Ubuntu 9.10 is running with older PC hardware. For the testing in this article we pulled out an aging laptop and ran a set of tests across Ubuntu 8.04.3 LTS, Ubuntu 8.10, Ubuntu 9.04, and the latest Ubuntu 9.10 snapshot.
