Could you give us an idea of how you get such a large TAGS file?
Emacs's Lisp directory weights in at around 60MB, and its TAGS file is
about 3MB, so assuming a similar ratio, your 1.8GB file seems to imply
that the indexed code of your project is more than 30GB in size, which
seems rather unusual.

Do you also index files which are not human-written, maybe?
