For the most part, these tests don't show Windows 7 soundly trouncing XP. But for an operating system that's far richer in features and more advanced in interface, Windows 7 is quite close to the older OS and tops it in several tests. Most impressive among Windows 7's wins were its JavaScript and shutdown time results. Maybe most telling was that Windows 7 beat Vista on every test. But to that much-belittled OS's credit, Vista actually shut down faster and performed 16 percent better on SunSpider than XP, even if it took significantly longer to start up.
