Windows Vista Service Pack 1 (SP1) is not measurably faster than the original stock edition, a Florida-based developer of performance testing and network metrics software said today. "Microsoft has hinted that SP1 is faster than Vista RTM," said Craig Barth, the chief technology officer at Devil Mountain Software, referring to the release to manufacturing version of the operating system. "But we found pretty much nothing measurable. It surprised me as much as it surprised everyone else, but the numbers are the numbers."
Devil Mountain ran its DMS Clarity Studio framework on a laptop Barth described as a "barn burner" -- dual-core processor, dedicated graphics, and either 1GB or 2GB of memory -- to compare performance of the SP1 release candidate that Microsoft Corp. released last week with the RTM version that hit general distribution last January. The Vista RTM was not updated with any of the bug fixes, patches or performance packs that Microsoft has pushed through Windows Update since the operating system's debut.
