ghc low-level code optimization cannot be compared with best modern C compilers that's result of 20 years of optimization. ghc generates machine code in rather simple idiomatic way, so it should be compared to non-optimizing C compiler another haskell compiler, jhc, generates idiomatic C code, that therefore can be compiled by gcc to efficient machine code. but overall jhc is pretty experimental compiler ATM -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
