The "Cheap Concurrency" benchmark at 

is pretty close to what Joe had, except it stops at
3000 threads, IIRC because going higher would break
too many language implementations (it used to be 500
threads, but I guess things have improved. See e.g.

You can play with the shootout page, and make 
comparisons between different languages. The 
following view compares Erlang with JDK and 
Scala (Java-based) and Python (since there
was another slot).
