One of the most compelling yet not properly accomplished tasks inside the distributed multimedia database arena is that of suitably fulfilling the disparate temporal requirements commonly imposed by the different types of persistent multimedia information. In such regard, an object-based multimedia management layer has already been conceived and implemented as a CORBA service towards the seamless integration of multimedia databases with "nethidden" media-dedicated storage repositories. The goal of this paper is to present some quantitative results obtained through measurement sessions over a developed prototype of this distributed service in order to qualitatively assess the adequacy of its architectural proposal.
