The question of performance is a decisive element in systems design. All kinds of considerations go into the logical machine design, from implementation details to migration policy. As the DLMS involves a serious overhead by migrating the LMOS among with the user processes, the uses of logical machine migration might not be in an environment where multiple migration in short intervals occurs. On the other hand, if the frequent migration of a whole group of processes is a system's specification, the logical machine migration reduces overhead compared to process migration.
