Which version of the image are you running?
Have you checked what Squeak is doing (->Process browser)? Maybe the  
weak array finalization process is taking up all the cycles...
Also, in the beta version of 3.9 there was the higherPerformance  
preference turned on (->Preferences higherPerformance) which on one  
of our old test server made the image idle at around 30% IIRC!
