thread cpu utilization

if you just want to know the CPU utilization as a tool for guiding
optimization efforts, you may find the kernel debugger useful. The
thread info display (using the "lp" command, then selecting a thread via
cursor keys and pressing return) shows the duration the thread was
executed, e.g.:

  cpu time: 215.000 ms

To make the retrieval of the consumed time per thread more convenient,
there is the following patch by Christian Prochaska. It displays the CPU
time directly in the list of present threads ("lp"):
