Using the multi interface it already shares connections and DNS cache
automatically and then there's not much more to share. The easy struct has a
bunch of variables for internal house-keeping and then there are the buffers:

There are no less than three buffers allocated at CURL_MAX_WRITE_SIZE (16K),
so 16*3=48K is "wasted" there already. You can of course:

  1 - change the code to alloc the required buffer(s) once they're needed, as
      the upload buffer is rather pointless without uploads and I believe the
      master_buffer can be skipped if not using pipeline...

  2 - experiment with lowering the CURL_MAX_WRITE_SIZE value, but that might of
      course also risk getting a slower throughput.
