It shouldnt have too big cost unless you are really RAM constrained. (read running: a 32 MB system or so) So it's a nice tool if you want to see a general categorization of latency sources in your system.

latencytop is certainly useful enough so that several distributions enable it by default. It has size impact on task struct but otherwise the runtime cost should be near zero.
