Programmers often need to use distributed algorithms to add non-functional behaviour, such as mutual exclusion, deadlock detection and termination, to a distributed application. They find the selection and implementation of these algorithms daunting. Consequently they have no idea which algorithm will be best for their particular application. To address this difficulty the Algon framework provides a set of pre-coded distributed algorithms for programmers to choose from, and provides a special performance display tool to support choice between algorithms.The performance tool is discussed in this paper. The developer of a distributed application will be able to observe the performance of each of the available algorithms according to a set of of widely accepted and easily- understandable performance metrics and compare and contrast the behaviour of the algorithms to support an informed choice. The strength of the Algon framework is that it does not require a working knowledge of algorithmic theory or functionality in order for the developer to se the algorithms.
