The 1988 paper, "The Limited Performance Benefits of Migrating Active Processes for Load Sharing," concludes that migrating active processes for load balancing offers little additional performance benefit beyond that obtained using only remote execution (placement). This result is based on analysis and simulation of a system model that is intended to overestimate the performance benefit of migrating active processes.

This note examines the system model used in the above paper and concludes that (1) it does not describe many systems, like networks of workstations, to which its results have been applied, and (2) that it underestimates the potential performance benefit of migrating active processes.
