In other words, it isn’t so much that WMP is using too much time, but rather that it’s using it in big enough chunks that overall system responsiveness deteriorates. Is it really consuming such an outrageous amount of CPU time? My guess is that latency is more of an issue than throughput. Why is WMP such a performance-killer in Vista? Just because it has a blank check doesn’t mean it runs when it has nothing to do. This is because priorities are static in Windows, so moving one task’s priority past another’s could have a sudden and dramatic effect. Two sliders would be ideal, but in practice, a priority slider would have surprising behavior. But if the bias is static, then it must be adjustable. I realize that it’s useful to be able to prioritize a single application over anything else. More importantly, though, it doesn’t appear that the priority level or the timeslice cap are tunables. This approach is a blank check rather than a structured settlement. In most systems, even dating back to the 70s, priority and timeslice are manipulated incrementally and dynamically to provide balanced behavior as a task because more sleepy or more hoggish. First, any task with an extremely high static priority and timeslice ratio will severely degrade overall system responsiveness.
I disagree with this approach for several reasons. If WMP becomes CPU-bound, it is designed to run in 8ms chunks, leaving the rest of the system with low throughput and extremely high latency. In other words, it almost always runs while it has stuff to do. WMP runs as a real-time (high priority) task capped at 80% of each timeslice. The scheduling framework is really simple, and has been well-known to the public since last summer. I think MS trusts third-party companies a little too much…

Before that, it was not including memory protection in Windows 95, as there were legitimate uses of it and any company whose products abused it would quickly kill themselves in the market and become dead weight on the shelves. They predicted that any site that maliciously used popups would be quickly abandoned by the Internet community, and that sites that used pop-ups as they were intended (to provide information for applets, f’rex) would be punished for other’s sins by including a pop-up blocker in IE4. We all remember back when popup ads first reared their ugly head how Microsoft declared that they would not be adding a popup blocker into IE4. The abuses are just too powerful I would think that there would have to be a whitelist to be allowed to use this priority, at least one controlled by Microsoft if not one controlled by the enduser. What I worry about is the ability to declare yourself as a ‘user-critical’ process is essentially unrestricted, an on-your-honor thing. I don’t see that as a flaw (maybe because I’ve never seen the behavior you describe). It isn’t a problem with earlier versions of Windows (NT). If Vista has problems with this it says more about Vista. Works fine in Win2K, XP, Win2K3 and my gentoo installation. converting movies, moving several GB of data, and downloading through several clients – all at the same time. But it’s perfectly possible to have many programs running in the background, incl.
On Linux I haven’t noticed any problems so far, except for the combination of music playback and Nautilus hanging.

On Windows only WinRAR has managed to create issues – or starting applications while watching movies (which happens rarely due to the passive nature of movie entertainment). I can even move the film I’m watching without any hiccups. I don’t have problems with playback even when moving many GBytes. If that’s enough to make playback stutter you’ve got to fix your setup. That includes, but is not limited to, copying large amounts of files to/from the computer that is playing the video.
