The paper is called "4bsd Unix TCP/IP and VMS DECNET: Experience in Negotiating a Peaceful Coexistance" (p323-5) by Van Jacobson et al of Lawrence Berkeley Labs. They are working with an early version of SRI TCP/IP (now a product of TWG). "We are still in the process of system performance investigation but have some preliminary results. It probably comes as no surprise (at least, to a Unix audience) that we find 4bsd TCP/IP has substantially better performance than VMS DECNET. In our tests to date, the Unix throughput has been higher and CPU utilization lower than VMS. The Eunice TCP/IP performance is not as good as the Unix performance, probably owing to the high `cost' of a VMS QIO. (...) We were suprised to find that, in most cases, the Eunice TCP/IP outperforms VMS DECNET in both throughput and CPU utilization."
