My practice is to use iperf with packet capture on both sides. The packet
capture can then be analyzed for accurate per-second, or less, throughput,
re-transmit rates, etc. This was implemented in a corporate network in
several ways including dedicated servers (that also did other monitoring),
and bootable CDs or USB sticks that a user in a small office could run on a
standard desktop. Many interesting issues were discovered with this
technique, and a fair number of perceived issues were debunked.

If you are doing this for yourself, as a network engineer, this is great.

But simple Joe at home doesn't care about all this fancy analysis. Does
he get a pretty picture saying "Yay", or "Nay", that's all?
