I just discovered that changing DiffArray to a plain Array improves performance of my code by almost a factor of 10. Bitten by DiffArray yet again!
John -- this is no good, just change DiffArray to Array. > update :: (Char -> [Int]) -> DiffArray Int ModP -> Char -> DiffArray Int ModP > update lookup arr c = arr // (map calc . lookup $ c) > where > calc i = (i, (arr ! i) + (arr ! (i-1))) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
