UBUNTU 14.04 We compare Ubuntu 14.04 Trusty Tahr to Ubuntu 12.04 Precise Pangolin to find out which is the fastest Operating System with HTML5, Octane, Peacekeeper and Sunspider. We will also be testing the Operating Sytems to find out how quickly they start up and shut down. We are testing Ubuntu 14.04 and Ubuntu 12.04 using the Firefox 46 with AMD Athlon II X2 240 CPU."
