Didn't know what the cause is, but CPU usage of Cinnamon never goes
above 10% , even if I stress a lot with window moving pop-up/down, etc.
Also MEM usage is with more then 700MB (firefox, evolution, geany, etc.
opened) moderate.
With kernel 3.4.xxx-rt there are no problems/Xruns at all.

Broken or not, I'm not as fast as you, to diss a Application/DE or what
ever. Sure there is something wrong in Cinnamon, but, I'm sure that it
could solved, as soon one find out what it is.
Otherwise, Cinnamon is a nice looking Desktop, with nice effects and 3D
impression on the screen.

For now I know, that if I need to switch to never kernels, I've to
switch back to LXDE or a similar lightweight desktop.
