He started by writing that he created a 192MB file of random data,
which means Emacs uses at least that amount.  

If that is typical of the kind of data Herbert work with, he may very
well be best served by using another tool.  'sed' is actually
optimized for the kind of task he have used as examples, so that would
be a good choice.
