I don't know whether you are particularly interested in the case you presented. For performance comparison between D and other languages in general there is this article that I think is quite good: http://janus.cs.utwente.nl:8000/twiki/pub/Composer/DotNetGeneral/csharp-performance.pdf
It is allready quite old and stems from 2003. Would be interesting to see how the repport would like like today when the benchmarks were redone. As your example suggested these number crunching-oriented benchmarks as in this report are not always that meaningful for everday life performance issues.
