The aim of our study is to optimize the execution of distributed object-oriented applications by positioning the components in a manner to optimize resource use. Placement of distributed applications is an open issue. In the context of distributed multiuser environments, where an application can not assume the behavior of the others, placement must be directed by the system to achieve this aim. Indeed, the system can dynamically observe behaviors of the applications and propose a placement. Placement decisions must be driven from two main factors, namely the computer and the network loads. In this paper we present an evaluation of a multicriteria placement manager that we implemented in a CORBA compliant system.
