Hello Chris,
I am not sure real value of using an iperf server other than one run by
your ISP because presumably if you use a third party the speed can be
affected by the upstream speed from that server.
The server I used in the script was the first one on a list I found on
Wikipaedia to respond to a ping.
Your ISP might have their own iperf server but as my ISP is BT I can't
get that info out of them without a phone call which will result in me
needing a three week break at a Buddhist retreat to calm down again.
