In my conclusion I mention why there are no benchmarks, it's nearly impossible to construct a realistic comparison between the two techniques.

When I cosnider tracing GC my primary arguments against it have nothing to do with performance at all, yet it often comes up as an argument against my position. This article is attempting to address that critique, by saying I doubt you could compare the two directly.

You "mention" this as if it were fact, yes. Apparently you are not aware of realistic comparisons that do exist, such as http://www.cs.utexas.edu/users/mckinley/papers/mmtk-sigmetri... (Alternatively, the article needs a discussion of why you think this is not a "realistic comparison".)

The evidence is that all high performance garbage collected languages use some form of generational collectors. These implementations aren't made by idiots.
