[erlang-questions] Erlang vs. Stackless Python

Well, sure. The ring benchmark serializes all processes,
which means that there is practically no parallelism in
there.
 
There's a similar benchmark, called big.erl (big bang),
where a thousand or so processes are created, and all
start talking to everyone else.

It gives excellent speedup on SMP Erlang.
 
That might be another good benchmark to try in other
languages.
 
BR,

	An interesting result was that the -smp flag caused erlang to
slow down for that test.  Should that ever happen?

		Indeed. There's a longish discussion on hat in the
comments. It looks
		like erlang is unbeatable still :)
