Hello, Where there were no entries to the http://shootout.alioth.debian.org/benchmark.php?test=chameneos&lang=all benchmark, there are now two. The one by Josh Goldfoot is already posted, the one Einar Karttunen and I optimized has been submitted and will run faster/smaller. Our code is at http://haskell.org/hawiki/ChameneosEntry Now for improving the fasta benchmark, http://shootout.alioth.debian.org/benchmark.php?test=fasta&lang=all , which currently has a space leak in the Haskell entry. A non-leaking version which has been optimized to run 3.5 times faster is now up at http://haskell.org/hawiki/FastaEntra (ooops..my spelling mistake). It could still be made to run about 3 times faster, if the other languages are any guide. Anyone want to help polish this one? Also, two other existing entries have space leaks, as can be seen at http://shootout.alioth.debian.org/benchmark.php?test=all&lang=ghc&lang2=ghc And finially, the haskel entry for http://shootout.alioth.debian.org/benchmark.php?test=fannkuch&lang=all is currently the *slowest* entry out of 28 languages. It is 813x slower than the c-code, 500x slower than OCaml. Should be easy to make it faster... Cheers, Chris Kuklewicz
