Data throughput testing

why the packets are getting fragmented from upf while testing with iperf and throughput of Downlink is also is less compared to Uplink?

Hi,

Can you please attach the pcap file with detail description of the test.
Thank you!

Hi, how do you do the performance test with iperf? I wanna do some performance test but don’t know how to start. Would you mind teach me the usage?
