We consider a simple primitive that corresponds to a communication round in which every host sends messages to every other host; this primitive occurs in numerous distributed algorithms. We experiment with different algorithms implementing this primitive. We run our experiments on ten hosts at geographically disperse locations over the Internet. Our analysis provides insight into some of the factors that affect distributed algorithms' performance, and how these factors come into play. Our study also identifies which algorithms are best suited for various different circumstances. Based on joint work with Idit Keidar. -----------------------------------------------------------------------
