Vista DRM and Performance

Six months ago there was a fuss when Peter Guttman published his article on the Microsoft's new operating system Vista and how its DRM implementation could disrupt computer system performance when DRMed media is being played. Now the crows are coming home to roost.

In the last week there have been reports that Vista networking performance drops to 5% of maximum when the music player is active and 10% of maximum when any visual media player is active. This appears to happen even although the media player is paused, and even on multi-core systems where you might expect other cores to pick up the load. For example:

I have a Q6600, and while experiencing this crappy network performance, all 4 cores are practically idle.

So what will be the conclusion of all this? Microsoft has had many products that have knocked it out of the ball park, but every company produces a duff product now and again. It looks like Windows Vista could become the Windows ME of the 21st century.
