I believe it's, at a minimum, a read of every byte in the file.

Assuming you already know one of the files' checksum (the text-base),
that would probably be faster than a byte-by-byte comparison of two
files when the files are identical. When the files differ, I guess
the cost differences depends on how close the beginning of the files
the first difference is.
