The following commands were run to gather the results on this page:
{{{
/usr/bin/iperf -c $serverIP -t 60 ; sleep 60
/usr/bin/iperf -c $serverIP -t 60 -P 5 ; sleep 60
/usr/bin/iperf -c $serverIP -t 60 -P 10 ; sleep 60
/usr/bin/iperf -c $serverIP -t 60 -u -b 100M ; sleep 60
ping $serverIP -q -c 60
}}}
Note that a 60 seconds delay was used between test runs.
