Hi, James. Because "String" is represented by the "[Char]", each element of String is allocated individually. ByteString represents a string in a single array and hasn't overhead for allocating each char.

Hmm. I read somewhere that GHC optimizes it to handle it more as char * if possible. Could anyone clarify it? Regards
