The ZEUS program came about because our VAX environment is heavily loaded with people developing programs (using EDT) and people run some very heavy duty cpu-bound type programs (interactively). It cause the interactive users who are trying to edit or such other io bound things to grieve quite a bit. So ZEUS is a background program which monitors the interactive processes (those with terminals) and lowers the priority of those processes which are cpu-bound. The interval of ZEUS scan is set such that it uses approx 1-2 % of the cpu. For us, this is worth the overhead since we do not have to monitor the system continuously to see who is hogging the system and it gives the interactive users better responses.
