![]() The experiments were repeated across one outlet in each room of the house, and transfer rates corresponding to the worst performance are reproduced in the table below. The average of the time taken to transfer each file was recorded. We set up 5 files of varying sizes (5 MB, 700 MB, 1.4 GB, 4.37 GB and 16 GB), and transferred them from one computer to the other four times. It is quite well known that nothing can be as inefficient as the Windows SMB network sharing protocol. Both machines were running Windows 7 and the hard disks had more than enough performance to surpass the 100 Mbps rate at which the interfaces were capped by the powerline kit. The kits were connected to the two power outlets to be tested and two notebooks with GbE ports were connected to them to set up a P2P network. We decided to do nothing fancy in our benchmarking methodology for the WD Livewire. As expected, they gave similar sort of benchmark figures as the WD Livewire. On the other hand, we did manage to lay our hands on a couple of other Atheros/Intellon based powerline adapters. Unfortunately, we are not in possession of a Belkin Gigabit unit. Ideally, we would have liked to benchmark the WD Livewire against a product based on a chipset from Gigle Networks. It is not the case for a consumer that one powerline networking product performs better than the other. ![]() The other issue with powerline networking products is that most of them are based on the same chipset, and offer similar performance. The main issue with powerline networking is that it is heavily dependent on the usage environment.
