We present a simulation model used to evaluate a distributed search engine by modelling its performance. The model is designed to aid performance-driven evolution of the system. We present the results of simulations investigating the architecture of the system and how it will behave when scaled up, and show how the simulation gave insights into the behaviour of the real system.
