The latency time is 13.9ms on a 4kB page system, 20.8ms on an 8kB page system, and 36.9ms on a 16kB system. By comparison, Sprite Douglis91 dynamic process migration takes 330ms. This thesis shows that process migration latency costs are now a small fraction of the demand page operations across the network. The analysis also reveals further potentially large savings in both process migration latency and cross network demand paging. The thesis demonstrates the negative impact of increasing overhead on system load sharing speedup through experiments with different overhead costs.
Small overhead is essential for good speedup.
