The problem is not Haskell, nor is it the implementation. The problem is that beginners, including yours truly, tend to write awfully inefficient code once you give them a "String" and tell them: Here, that's the contents of your file. The lazy API hides the fact that I/O takes place, and it is very tempting to forget that you shouldn't use it like a random access list. The lazy API "encourages" you to write inefficient code.
Nonetheless, the problem is the inefficient code, not the language.
If the language encourages you to write inefficient code (or rather, discourages you from writing efficient code), I see that as a problem with the language. You mention the use of hGetBufNonBlocking to get better performance: would you like to rewrite all your code to use hGetBufNonBlocking rather than using e.g. stream-based lazy lists?
