/* The default upload buffer size, should not be smaller than
   CURL_MAX_WRITE_SIZE, as it needs to hold a full buffer as could be sent in
   a write callback.

   The size was 16KB for many years but was bumped to 64KB because it makes
   libcurl able to do significantly faster uploads in some circumstances. Even
   larger buffers can help further, but this is deemed a fair memory/speed
   compromise. */
