Hi everyone

Is there any settings or policy's I can use to make sure I am getting the best possible throughput? I have 2 sites linked via ATP800 and Flex700. Bother are on 1GB bearers up and down.

The best speed I get is around 1.4 megabyte per second. Any tweaks suggested would be greatly received :-)

    Trying to decrease encryption length. 
    I will also try to observe whether the WAN/LAN has serious packet loss during the transmission process. If so you will see many Dup ack/ retransmission / out of order in wireshark.

    Hi @DanniKool,
    Greeting Forum. Please kindly capture packets on LAN/WAN.
    We will analyze whether the packet is out of order
    Thank you

    I am new here and i just want to tell you that To optimize network throughput on sites connected via ATP800 and Flex700, you can implement policies such as Quality of Service (QoS) to prioritize traffic, ensure proper bandwidth allocation, and reduce latency. It's also recommended to optimize network hardware and firmware, monitor network performance regularly, and troubleshoot any issues that may arise.
