Domus is an architecture for Distributed Hash Tables (DHTs) tailored to a shared-all cluster environment. Do mus DHTs build on a (dynamic) set of cluster nodes; each node may perform routing and/or storage tasks, for one or more DHTs, as a function of the node base (static) re sources and of its (dynamic) state. Domus DHTs also ben efit from a rich set of user-level attributes and operations. pDomus is a prototype of Domus that creates an environ ment where to evaluate the architecture concepts and fea tures. In this paper, we present a set of experiments con duced to obtain figures of merit on the scalability of a spe cific DHT operation, with several lookup methods and stor age technologies. The evaluation also involves a compari son with a database and a P2P-oriented DHT platform. The results are promising, and a motivation for further work.
