Re: Re[2]: [Haskell-cafe] Big Arrays
Just out of curiosity, may I know a use case of such huge arrays? At such sizes, I thought, the array would not have the expected array properties (constant access time) due to thrashing. thanks, Hemanth ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I don't see how using 'Int' instead of 'Word' makes array access several times faster. Could you elaborate on that? The important limited use case is an array of Word8 -- by using 'Int', byte buffers are artificially limited to half of their potential maximum size. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
