I'm trying to doing some bandwidth test by run iperf on my device,

My Network Max Bandwith is 100 Mbps 
(test by speed test CLI - <https://github.com/sivel/speedtest-cli>)

And I ran the iperf UDP bandwidth test 
(like this $(iperf3 -c $server\_ip -u -b 500M ))

And then I get the result 
(almost 500Mbps in client side message)

Is the result right ?

All the possibilities now I think is that the client side iperf is just calculate the sender bandwidth (because of UDP)
