Packet loss during iperf3 test

ashiqpathan commented 2 years ago

Issue Description

I have configured 5G NSA END-to-END(https://docs.srsran.com/en/latest/app_notes/source/5g_nsa_zmq/source/index.html#g-nsa-zmq-appnote). I am using open5gs as the core network. I am able to connect ue to gnb. But using iperf3 I am getting very low throughput and a high data loss. An iperf3 screenshot is given below-

I have a total 3 VM,

Iperf3 with 100Mbps BW produces high packet loss around 94% drop. What might cause this behavior? Why the throughput is limited ??

It could be the issue of ogstun of open5gs. You may try sudo ethtool -s ogstun speed 10000
