On the old instance it is a stable 2% and on the new it is 1-1,3 %. That was the reason making me looking at it. I was so used to the 2 % I spotted the difference immediately.

And on the same time the images moved from an ubuntu 12.04. system to a ubuntu 14.04 system. Looking at the top command it appears the images/vms need noticable less CPU or better the tools report less. The monitored overall CPU usage also is much lesser than before.
