I love having multiple DEs on my linux laptop... I currently have Unity, Gnome3, gnome classic and Openbox. Would this mean slower performances? Thanks a bunch!

Gnome 2 and Gnome 3 would be a bit problematic. Gnome 3 and MATE (fork of Gnome 2) should work though. – RobinJ Nov 12 '11 at 12:44

No, installing and keeping different DE's does not mean slower performance. But when you are on a DE, you can try to avoid using an application which loads the other DE's modules, libraries etc.

Using multiple DE might affect the stability of the OS because some of the DE come with its own dependencies. I use unity, Gnome, gnome classic, gnome metacity, gnome compiz and cairo dock but on start up i choose a specific environment i want to use and use it rather than mixing them up.
