Performance - Maximum
Belkin first had me upgrade the firmware with the recently-posted 22508 Beta firmware and I started by running separate transmit, receive and simultaneous transmit/receive tests in Location A (plugged into the same outlet). Figure 5 shows a composite IxChariot plot, which shows an aggregate transmit / receive throughput of around 180 Mbps vs. about 120 Mbps in each direction.

The higher simultaneous throughput prompted me to run a few more tests with more simultaneous streams. Similar to what I found with MoCA testing, throughput increased with multiple streams. It topped out around 300 Mbps using six simultaneous streams (Figure 6). This was much better than I found with multiple MoCA streams, which topped out just shy of 140 Mbps with four simultaneous streams. It is also the highest throughput I have ever seen from "alternative", i.e. non-Ethernet networking!

In contrast, the NETGEAR XAVB1004 pair produced only 61 Mbps total throughput with receive and transmit running simultaneously and about 45 Mbps in each direction (Figure 7).

Speed did not increase with additional connections however, as Figure 8 shows.
