It could be that the number of chunks is slowing it down more the the
total size of the chunks.  There is a fair amount of processing done to
create the header and footer navigation for each chunk.  Plus the chunking
process has to determine the destination filename for each cross
reference.

The stylesheet below isn't very practical but will show how much time is
saved by skipping much of the chunk related processing.  It cut the time
in half on some books I tried.
