I don't think you'll find performance tests which are worthwhile. As pointed out NH (and EF) performance varies as you use them. With this in mind, you should optimize according to your usage. Try looking at differences in the generated SQL between the systems and configurations to see if there is something there. Otherwise code profilers could tell you where the systems are spending their time. However, if you are going to optimize your NH code just to win the argument and convert, it's not really fair if you don't do the same to the EF code. Ultimately, if the only way to convice people to move from EF is through performance, I think you're better off looking at one of the other ORMs which have speed as a selling point.
