Since inputString is large you really should avoid causing it to be copied over and over again
I agree wholeheartedly, the autorelease pool "solution" is a sticking plaster on a gaping wound. A better approach is to avoid the need for it in the first place. I'd also say that this looks like a O(n^2) operation which might be slow given the file sizes you mentioned. If this is being run on the main thread you might need to give some thought to keeping your app responsive, maybe by breaking this down into shorter chunks (or shunt this off onto another thread - it looks like a reasonable candidate).
