Upload speed gradually slows down

Expected behaviour

Uploads occur between 10 ~ 50mbps

Actual behaviour

Uploads starts with 500mbps and gradually slows down to 1 ~ 2 mbps

Steps to reproduce

  1. Move a file to owncloud directory at Windows
  2. Open owncloud to start files sync
  3. Move cursor up to green bar, showing upload speed
