And there I managed to double throughput using 9k jumbo frames, alas still far shy of the theoretical maximum. Jan Just enabling jumbo frames on devices on 2 sides of the link won't do anything - you will allow larger packets through the link, but nothing will be sending those packets. When the jumbo-framed transmitter sends it to the non-jumbo'd receiver, the the receiver will drop the Ethernet frame. If the line quality is good and packets are getting through okay then a larger window size (larger window = faster transfer) is negotiated. Now add the 12-byte Ethernet frame header, two bytes that identify the Ethernet type, and four bytes of error-detection data and you get a standard-sized Ethernet frame of 1,518 bytes.
