One can never be 100% sure, but your application is numerical and
experience suggests that numerical code can often be optimised to yield
code similar or better in performance than C.  The pseudoknot benchmark
(a while ago now) was a good example.

I didn't mean to give that impression, sorry.  Optimising Haskell code
is a delicate art which requires experience and sometimes a deep
knowledge of GHC's optimiser.  This is a real problem, and we readily
accept that.
