Comment (by warner):

 I can imagine two problems here.. which are you thinking of?

  * SFTP only uses SDMF so far (I think), so maybe MDMF uploads use more
 memory than SDMF, regardless of how the data gets to the gateway
  * the webapi path holds temporary data in different ways than SFTP does
 (in which case we'd be comparing SFTP-to-SDMF against webapi-to-SDMF)
