TESTING METHODOLOGY

   As already mentioned plenty of times in the past the performance of Powerline adapters is directly linked to the quality of the buildings electrical grid/wiring so the output speeds from such devices will most probably vary between new and old structures. Still the results recorded when testing Powerline adapters inside the same building should easily point out the best one and so to that end we used the well-known Passmark Performance Test to measure the data transfer rate in wired, wireless and Powerline modes with a fixed (for every test) distance of 15 meters between our Netgear DGN3500 Gigabit modem/router and the primary and secondary systems (30m in total between both systems). The network data transfer test was set to duration of 40 seconds and was repeated a total of 5 times after which the average numbers were recorded into our charts. As a secondary test we are also using QCheck by Ixia which is considered amongst the top measuring tools of its kind. Tests were also performed a total of 5 times at throughput mode with a data size of 1000Kb and in the end the average numbers once again get recorded into our charts.

TEST RESULTS

   Passmark didn't seem to like the dLAN 500 AVPlus Powerline adapters at first, something which coupled with the number in the cockpit program (137Mbit/s) really made me think that something was wrong. So i also used the latest QCheck version by Ixia with all the units i have here and although it did offer a slight performance jump still it was nowhere close to the performance displayed by the cockpit program (i really can't say why that is).
