But you have to take these results with a grain of salt. Both the Perl and Python tests are implementing binary trees in vanilla Perl and Python. Both Perl and Python have performant libraries written in C which is what you would use in a situation like this.

Well, that's how you judge a language. You write code in it, as opposed to writing it in some different language not under consideration.
But a much worse problem seems to be the fact that binary-trees is not much of a representative benchmark. It's mostly a benchmark of your memory management. Unless your programs spend 80% of their time managing memory, they'll probably not match the results of binary-trees.
