It would be interesting to know if the engine were doing lots of encoding conversions in order to test for the string. I must have missed the first email but I’d be interested to know if the file was opened for text or binary read and if an encoding was provided in the command if it was text. If it was binary is performance any better if the until <string> a variable with the same encoding as the binary file? The other thing worth pointing out is if you are doing a text read on an 8 bit encoding the size of your data doubles once read because each character is represented by 16 bits. When you consider the amount of data we are talking about here that will cause a serious slowdown.
