No, that's not a fair comparison. Paging/swapping is the only way to extend virtual memory space without buying more RAM. Is there an alternative method of increasing VM size without paging, and is it any faster? Also, typical programmes don't suffer much performance loss with paging.
DSM is not the only solution to parallel/distributed computing. DSM can destroy performance for typical threaded programmes. Typical MPI programmes will work fairly well on a cluster.
