XG to XG RED tunnel optimization

Carlo

Hello,

Can I do anything to improve RED tunnel throughput between local XGS 2100 on 1000/500 WAN link and virtual XG firewall running in Azure? Enable/disable compression does not change anything as far I can see.

     Actually when I run .

    .\iperf3 --client 10.2.0.6 --parallel 25

    I get much better result

    In General, multi download streams are faster than a single connection. But this could be a limitation of the iperf and not the general tunnel. What if you try another protocol to download something? 

    You could try to decrease/lower the MTU of the RED tunnel. 

    Decrease to 1400 on both ends and redo the tests.

    I would not say that this is iperf limitation because when I test local network I get good results.

    Results with 1400 MTU are same
