I did see a comment like that, but at first glance I didn't read it correctly.
I think it actually said something more like - Haskell is X times slower and Erlang is Y times slower than C.

Fasta? What a strange choice!
Oh! Could it be that none of the tests before Fasta show a C program as fastest :-)

Another sequential program ;-)
(At least spectral-norm keeps all the cores working.)

I doubt the person who made that comment on the Computer Sweden website actually was concluding something from looking at the benchmarks game web pages.
It seems more likely that they went through the web pages looking for some measurement they could use to demonstrate what they already believed.
The salutary lesson is that we all seem to have a weakness for ignoring contradictions to our beliefs and seeking confirmation for our beliefs.
