Yeh I have to admit, for a distro claiming to be for "studio" use, there are a lot of performance tweaks which should (IMO) be applied, which are not. For example, when I install UbuStu on my new PC, it detects my nice 3D card and turns on all the flashy compiz effects. That shit should not even be installed on a DAW. I think that Ubustu is really more of a collection of studio related apps on top of a normal distro, than a real studio distro. Still, even out-of-the-box, it needs less tweaking than windows for the same purpose ;)
