I would question the wisdom of using any generic benchmark (such as the
"console output test" you included) to make decisions about adoption of
key technologies.

Identify the core characteristics of your intended application, code up 
a simple benchmark which contains representative code, and see how it
stacks up against the competition.

We did this with Python on one embedded system we were considering,
with a benchmark that included threading, memory allocation and releasing,
some simple math, and lots of string operations.  The results told us
much more than PyStone or something similar would have, and gave us much
more confidence in the results.

And with Python, of course, it's almost trivial to do this kind of 
thing, compared to some other languages.  Sigh.
