iperf3: abrupt interval display

[nikitarulz]

While checking network performance using iperf3, I'm facing interval issue at client end. Below are the logs:

I checked github bug #125 which was addressing this specific issue. But no help.
I have tried iperf3.0.5, iperf3.1, iperf3.3, iperf3.5. In all versions, I'm getting the same issue.

P.S. Server(with same iperf3 version) provides result as expected with 1 sec time interval, but client provides data at different time intervals in every iteration.

Kindly look into the issue and do let me know if m missing something.

I see where you posted this question to the iperf-users mailing list as well, which was actually the more correct place to ask. I'm going to close the issue here and reply on the mailing list.
