In this paper we study three basic and key issues related to Web query processing: load
balance, broker behavior, and performance by individual index servers. Our study, while
preliminary, does reveal interesting tradeoffs:(1) load unbalance at low query arrival rates
can be controlled with a simple measure of randomizing the distribution of documents
among the index servers,(2) the broker is not a bottleneck, and (3) disk utilization is higher
than CPU utilization.
