Those lines mean that your transfer wasn't stable (due to networking
or your hardware). In the first lune you see that the test took 10s
(0.0-10.0 sec) and iptraf transfered 1.11GBytes so it's 963Mbit/s. The
second line is the same test but in the other way (due to "-r" option
in iptraf). It can tell you that either one PC is sending the data way
slower or the other is receiving it slower than the other one or maybe
that just your network isn't just that stable to sustain 1gbps
throughput for a longer time.

To get more reliable results use -t 60 to test for 60 seconds and with
-i you can change the reports interval i.e. to "1".
