Linux Well, this is quite interesting. This is one of those items where I have to make sure everybody realises I'm no developer as to not make myself look like an idiot. Having said that - LinSched. It's a user-space program that hosts the Linux kernel scheduler, so you can create and test scheduling policies on arbitrary hardware topologies - without actually having to work with the real hardware.

RE[3]: The Problem...

Take my Windows 7 box as an example : when a backup is running, as scheduled regularily, if I try to play music with WMP, I'll get choppy playback. And, worse, every time music playback hangs, the rest of the UI hangs together with it.

Does it mean that I, as a user, should give up on scheduled backup or on music playback in the background ?

I still don't get why we still have those problems. I give my OS 6GB of memory, 4 cpu cores at 3GHz, 1 SSD and 4 2TB harddisks. And still things like watching a 100MB video file will be extremely choppy when I do large moves from one harddisk to the other.
Is there no genius that can solve this? Or do we let SSD's solve the problem like we did with quad cores?

The problem is not hardware resource, it's the way they are distributed. With better scheduling, we would get a smooth experience on anything that's not totally IO-bound.
