    Is there any spec for reference?

    It is line rate.

    The packet forwarding rate for gigabit port =1,000,000,000bps / 8bit / (64+8+12) byte=1,488,095pps
    pps is for packets per second. It uses 64 bytes packet as the test standard of packet forwarding rate, and the 8 bytes are for preamble and start of frame. The 12 bytes is for the inter frame interval.

    Thanks,
    Ryan
