"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."

UBUNTU 12.04 FEATURES
"Enjoy the simplicity of Ubuntu's stylish, intuitive interface. Fast, secure and with thousands of apps to choose from, Ubuntu gives you a clean and streamlined experience that you can really make your own."
"Ubuntu 12.04.2 LTS is a long-term support release. It has continuous hardware support improvements as well as guaranteed security and support updates until April 2017."
"The use of PPAs for popular applications largely eliminates the need to upgrade to a newer distribution if you want to stay up to date with applications, so I personally don't run anything other than LTS releases outside of testing environments. Unless you want the absolute newest version of everything."
