Many of the solutions to the shootout test are using "imperative" Haskell. "Real" "functional" Haskell performs significantly slower.

Re: [Haskell-cafe] Why can't Haskell be faster?
Are these benchmarks still up-to-date? When I started learning FP, I had to choose between Haskell and Clean, so I made a couple of little programs in both. GHC 6.6.1 with -O was faster in most cases, sometimes a lot faster... I don't have the source code anymore, but it was based on the book "The Haskell road to math & logic". However, the Clean compiler itself is really fast, which is nice, it reminds me to the feeling I had with Turbo Pascal under DOS :-) I find GHC rather slow in compilation. But that is another topic of course. Peter Paulo J. Matos wrote: Hello all, I, along with some friends, have been looking to Haskell lately.

I don't know for certain that this is still the case (and if so why). But I do remember that when I was a Clean user a few years ago both the Clean compiler and the resulting executables were amazingly fast (certainly by FPL standards). I've often thought it's a real shame that two different but very similar languages exist. I think that the Clean compiler would be one of the best if not *the* best Haskell implementations available, apart from minor snag that it isn't Haskell at all :-) As things are at the moment ghc has no serious competition so we don't really know how fast it "should be". Maybe this will change in future. BTW, the reason I still jumped ship in the end and became a Haskell user instead had nothing to do with performance. The reason was that if I was going to invest a lot of time in progs/libs I wanted to have some confidence I'd made the right choice long term and I had issues with the Clean approach to concurrency (what the Clean folk call "deterministic concurrency"). I didn't (and still don't) see this as viable, but during a long and heated flame war on the Clean mailing list it became clear that the Clean team did not agree with my point of view, so things were not likely to change any time soon :-( Regards -- Adrian Hey ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Why can't Haskell be faster?
From what I've seen of Clean it seems almost like Haskell. It even distributes a Haskell->Clean translator so the obvious question is, why is Haskell slower? It's also something I've wondered about, and I'm curious about the answer... One of the differences between Haskell and Clean is how side-effects are allowed (Uniqueness Types for Clean, and Monadic I/O for Haskell) GHC also supports a lot of extensions beyong Haskell98. Does it explain the difference in performances ? I don't know... Experts please ! Manu ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
