I'm mostly using Erlang to solve problems at projecteuler.net. I'm not
sure if that qualifies as "real applications". :-) I think all of the
problems I've solved so far have exclusively been sequential
(calculating primes using Eratosthenes sieve, for example).
I'm comparing the runtimes with what other people are getting with
Java, Haskell, Php, Visual Basic, etc, and my Erlang code always seem
to take 5-10 times longer time to run. Of course, it could just mean
that I'm a lousy Erlang-programmer... ;-)

I'll run the corresponding program on my Linux-box and see what kind
of performance difference we're really talking about.
