A benchmarking comparison carried out by Florida-based Devil Mountain Software, found that Windows XP could be substantially faster than the newer Vista operating system, after a third service pack is released next year.
Devil Mountain Software compared a beta version of XP Service Pack 3 and Vista with Service Pack 1.
It found that XP, modified with Service Pack 3, performed twice as well as Vista modified with SP1. The Vista SP1 upgrade is due to be released early in 2008.
After upgrading with SPI, Vista’s performance increased less than 2 percent, while SP3 improved XP’s performance by 10 percent.
Devil Mountain ran the tests on a Dell XPS M1710 test bed with a 2GHz Core 2 Duo CPU and 1GB of RAM. Productivity tests were carried out, including creating a compound document and supporting workbooks and presentation materials, using Microsoft Office 2007.
In its defence, Microsoft said that the service packs are still in development and will evolve further before they are released.
The test results are likely to disappoint companies who have been waiting for the first service pack before deploying Vista, in the hope that it would address performance issues and bring it closer to XP.
Although Vista seems destined to remain slower than XP, its additional features, such as a cleaner user-interface with better graphics quality, plus enhanced security and search facilities, do go some way to making up for this.
