Ubuntu login analysis

I'm tracing a lot these days, and in the viewer, I need to scroll a lot to get to the interesting stuff in the control flow view. Today, I checked all these processes for fun. In fact, it's related to landscape triggered on Ubuntu login. To display the message about system usage and updates (which I think is great), landcape calls numerous sub-programs, for a total of about 250ms on my system. It's something one should keep in mind if SSH commands are repeated in a tight loop: the maximum rate is about 4 commands per seconds. Hopefully, Fabric reuses SSH connection! ;-)
