If you want to have fun, perhaps implementing a few emacs lisp library
functions in parallel (multi-threaded), could speed things up.

You'd have to find out what operations (particularly on big buffers) are
slow and parallelizable.

For example, replace-string could split its start/end range, (check the
cuts for occurences) and then process each range in parallel.

Similarly, replace-regexp and fontifying which is often thought to be
slow, could benefit (taking the same precautions around the cuts).

A lot of code that use iterative search (re-search-forward) could
probably be upgraded, using a function (such as re-all-matches) that
would perform the search in parallel on the different ranges.
