Scalability of RULE on workstation PCs

This technical report describes the scalability of the Remote Unix Lab Environment (RULE) system when deployed on workstation class PCs. Two different scenarios were tested: performing standard tasks using a shell and serving web pages with content sourced from a database . The RULE system was found to perform satisfactorily with up to 100 virtual hosts on a single workstation PC and RAM usage was found to be the main factor limiting scalability.
