You experience a high amount of packets being dropped when performing large data stream transfers (>50MByte/s).


Increase the ring buffer size of your network card:
  1. Check the maximum size of the receive (RX) buffer:
    ethtool -g eth0

    Example output:
    Pre-set maximums:
    RX: 4096
    TX: 4096

    Current hardware settings:
    RX: 256
    TX: 256

  2. Set the RX buffer to the maximum size:
    ethtool -G eth0 rx 4096
