In [1] we present the first analysis of Join-the-Shortest-Queue (JSQ) routing in Web server farms, with Processor-Sharing (PS) servers. Please see that paper for details about the JSQ routing policy and its analysis, and for the relevant references. The analytical work in [1] was backed up by many simulation experiments, not all of which made it into the paper. This document is meant to serve as an online supplement to [1], providing the full set of simulation results and comparisons with analytical results. We hope that these will be useful for those who wish to extend our work on this problem.
