Windows Vista lambasted over performance gains

As if potential lawsuits were not enough, Computerworld has revealed that Windows Vista might not be as fast as Windows XP after all.

Computerworld (opens in new tab), whose Save Windows XP campaign has garnered nearly 100,000 signatures, revealed the results of a number of tests comparing the Windows XP SP2 with Windows Vista SP1.

In the majority of consumer related tests carried out by Principled Technologies Inc on Behalf of Microsoft, Windows XP was faster than Vista and the gap between the two could have been more profound if the test was carried out with Windows XP SP3 was released earlier this month.

The tests were performed on four different computers (with 1GB of memory or more) including a tablet PC across a number of applications like Word, Quicken and Outlook.

Although the differences are very small in most cases, it will provide those, who are campaigning for Microsoft to continue to sell XP, with more ammunition.

Apart from Performance gains, Windows XP SP3 brings a few features that were available to Windows Vista and Windows Home Server 2008 owners only.

It is worth noting that behind Principled Technologies are two journalists that have founded the respected (and often feared) Ziff-Davis benchmark Operation which gave us Winstone.
