"We were pleasantly surprised to discover that Windows XP SP3 delivers a measurable performance boost to this aging desktop OS," said Craig Barth, Devil Mountain's chief technology officer, in a post to a company blog Friday.
Devil Mountain ran its OfficeBench suite of performance benchmarks on a laptop equipped with Office 2007, Microsoft's latest application suite. The notebook -- the same unit used in the Vista/Vista SP1 tests earlier -- featured a 2.0GHz Intel Core 2 Duo processor and 1GB of memory. The results reported a 10% speed increase under XP SP3 when compared to SP2, the service pack released in 2004.
