Microsoft alum Dave Plummer ran an implementation of the Dhrystone benchmark on all the vintage and modern computers he owns, including a PDP-11 and a VAX. The post in which Plummer reported the results (From 1976 To Today, Dhrystone Benchmarks Reveal How Far CPUs Have Come), which contextualizes the data and comments on the evolution of computers and software workloads, may be of interest to Kabir who is working on the Gabriel benchmarks.
