Re: [Iperf-users] UDP Datagram Count

[Bob M. <bob...@br...>]

Sorry, not a direct answer, but what version of iperf are you running? This

PS. One might want to try iperf 2 <https://sourceforge.net/projects/iperf2/>
as well. I'd suggest -e or --enhanced for more informative reports. This is
only for iperf 2.
