These results suggests that when considering Windows 7, performance should be viewed as a reasonable justification for upgrading from Windows XP, but not a driver for migration from Vista. (There are unrelated reasons to upgrade from Vista, as discussed below and in other articles on InfoWorld.) The flat performance results against Vista are reasonable given that, as we noted earlier, Windows 7 is based on the Vista kernel.
