functions used to make C code faster is obviously worse than those
used for Haskell code. just look - Clean gets 2x better performance
than C

my point is very simple - these tests says nothing about real
performance since these tests was hardly optimized including adding
special functions to ghc libs. amount of work required to do this is
much much more than amount of work required to write optimal C/asm

and this work obviously doesn't speed up every Haskell program. so
that we have in Haskell world now is heroic efforts to speed up
shootout test which doesn't say anything about real Haskell
performance. what we have on prcatice is 10-20% speedup of ghc 6.8 and
several libs which may improve speed in some usages
