[erlang-questions] benefits of binary format strings?

[Anthony Shipman]

The new R11B-4 has this change:

    OTP-6517  The Format argument of the functions io:fwrite/2,3 and
              io_lib:fwrite/2 is now allowed to be a binary.

Are there performance benefits from writing io:format(<<"hello world~n">>, []) 
compared with a bare string?
