With all due resepct, bollocks. The dispatcher is not tested at all here for example. To do a proper test add in some complicated url dispatch rules, session handling, various kinds of nasty hard-to-abstract-out business logic and we might be talking. The trouble is there you're then talking about a week's work to write each app. On the other hand the "benchmarks" are an interesting ultra-simple rosetta stone.
The comparison is reasonable as long as you test against an equivalent feature-set on each platform.
It might actually be an interesting exercise to gradually layer more features on top (such as the dispatcher chain and different templating/ORM layers) to discover inefficiencies in the various frameworks by comparing the relative performance impact.
E.g. if you involve the dispatcher and Django suddenly gets 20% slower but Rails only 10% slower then that might hint at an inefficient dispatcher-impl in Django.
