FYI: In the telcom world we try to drive our processors at about 75%. Cache hits are real important here. In our Tandem based Call Processing machines we typically run with 10 to 14 MB L2 cache and even after tuning near everything still get much better improvements just keeping something in cache compared to major rewrites on a functional basis. It is kind of interesting that we see the following repeated on various platforms (includeing embedded) under various workloads. 1/3 resources (time&space) for OS 1/3 resources (applications written by us) 1/3 resources for 1 or 2 purchased drivers or applications {^^^always the best but most complictated target for improvement}
