I am not sure how you figure this. I think a
$ dig @127.0.0.1 example.com axfr
will be far MORE efficient than a
$ cat /path/to/zonefile/for/example.com
In the former you are writing/reading an UDP socket on localhost,
receiving data which is in named's memory. In the latter you are
opening and reading from a file on disk, which, as noted by Mark,
might not contain all the data you need.

I suppose you know this already, but 9.8 is in EOL status.
