One day, I hope that high-level Haskell will outperform C all the time. It's already true with some of the ByteString stuff, but
i don't think so. all the tests where Haskell "outperform" C i've seen was just unfair - for example they compare results of MANUALLY-unrolled Haskell loops with rolled C ones - totally ignoring the fact that gcc can unroll loops just by enabling option while with ghc this can be done only by hand. many tests that show "equal performance" just limited by memory bandwidth. and so on it's hard to write program that outperforms gcc-generated code even using assembler, and ghc is limited to this fact, too :) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
