I have a pair of these to get an internet connection behind my TV. According to the web interface of the devices they are talking to each other at ~120Mbps. However if I run iperf over the link it tops out at under 10Mbps. Replacing the powerline bridge with a cable and keeping everything else the same gives a throughput close to 100Mbps.

Is there something that iperf does that powerline devices don't respond well to, or are they just not that good? If it's the latter, why can they hold a 120Mbps link but get nowhere near that once traffic starts moving?

Edit: It's not a huge issue since it's more than fast enough for Xbox 360, I'm just curious.
