Part of the Lecture Notes in Computer Science book series (LNCS, volume 1963)


In this paper we describe the main features of an implemented parallel object server that we have developed for storing fine grained objects. The motivation was to support a data repository of a CASE tool for a heavy-loaded multi-user environment and to test the suitability of parallel computers for this purpose. We present the results of our experiments concerning the speedup and the load balance of the system.
