A fair question.  I would expect that it would arrange to call write()
on an entire message, to avoid multiple packets.  I would be surprised
to see a deliberate attempt to delay between writes of different
messages.  I would try using ktrace/ktruss/strace or whatever and look
at the write messages and their timing.  (I realize you are asking if
anyone else really knows.)
