A patch was recently added to magit that let-binds
write-region-inhibit-fsync around the call to diff-refine-hunk, this was
reported to make a significant improvement in speed when refining all
hunks in a diff.  We should do the same for smerge-refine-subst (or is
it possible to do this automatically for all temp files?) before
extending diff refinement over the whole buffer.
