Hi Simon,
really performance-critical code. Also this will tell you whether your performance problems are due to strictness/boxing or something else. It should be possible to obtain the same performance as C++ (or better).
Are you shure about this? And why are you shure? You put the blame on me for the bad performance of my code, and i can let this hold - i don't think that i am a haskell performance expert (though i am learning a lot through you people - thanks a lot). But i want to know if it is just _theoretically_ possible or really easily feasible. See, i know of some C++ hackers who will eventually have to change to Haskell. This will get hard for them, and i don't know if they can get into complex performance issues right from the start :-) But i guess the C++ / Haskell comparison will look far better for Haskell when changing to computations with large data structures. All i can tell by now is that Haskell works fine for me while C++ is ... hard to program. Regards, Andreas Schroeder
