Windows Vista Performance Guide

Anandtech has an in-depth look at the new features and performance numbers of Microsoft's latest OS:

"When Vista first entered widespread public testing about a year ago, a series of screenshots were circulated showing the worst-case scenario for the number of operations required to permanently delete a single file. At the time it was six operations ranging from confirmation of the delete to granting security permissions to empty the recycle bin. To Microsoft's credit they've reduced that somewhat, but we can still replicate that situation and come up with a worst-case scenario that takes four steps. Two of those steps are the required confirmation for deleting the item and then emptying the Recycle Bin, but the other two are security confirmation steps and while it's admittedly nit-picking, it's overly redundant to require two security steps to delete a file; this makes it twice as hard as it is under any previous version of Windows. UAC security will be accepted up to a point, but even one more operation than is necessary is going to quickly cause UAC to end up disabled by those who know how to do it.
