That's strange. Compiled without optimisations, using plain Array instead of DiffArray gives a speedup factor of about 38 here, with optimisations it's a factor of 100 (thus it's about on par with the list-only version of the same algorithm). > > John _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
