Try to make this a newtype instead. The data type adds a level of indirection. > do let p j c = insertDAT a j c >> lookupDAT a j >>= \v -> v `pseq` return > () You most likely want (insertDAT a j $! c) to make sure that the element is force, to avoid thunks building up in the array. > -- Parameters > arraySize :: Int32 Int might work better than Int32. While they should behave the same on 32-bit machines Int might have a few more rewrite rules that makes it optimize better. -- Johan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
