I am not sure if this is as designed - loading 150-250MB files. I can an I/O error after a while or Cyberduck appears to merely stall. (uploading with SFTP) When I click STOP and then RESUME, the resume starts many MB earlier than the amount I have uploaded. i.e. if I have uploaded 90MB and total file size is 100; it appears to start at a random point like '5MB' - I sense that the spot it starts at is the FIRST ATTEMPT spot. i.e. it might have stalled the first attempt @ 5MB.
Is this as designed or can I do something to push it further along?
