Wellington, Fla.-based Devil Mountain Software ran several versions of XP and Vista through a test simulating common desktop computing tasks. It found the original Vista performed 50 percent to 100 percent slower than the prevalent XP Service Pack 2, or SP2.
In the coming 1st quarter 2008, Microsoft is releasing Vista service pack 1 and service pack 3 for Win XP. The fact is, Vista SP1 barely improved the operating system’s performance while Win XP SP3 increase the XP performance by 10 percents.
What this means is that Vista is getting slower while XP is becoming faster.
