Abstract
A simple efficiency preorder for CCS processes is introduced in which p≲q means that q is at least as fast as p, or more generally, p uses at least as much resources as q. It is shown to be preserved by all CCS contexts except summation and it is used to analyse a non-trivial example: two different implementations of a bounded buffer. Finally a sound and complete proof system for finite processes is given.
