We used PerformanceTest 6.1 by PassMark which you can find out more information about here. It has a handy Advanced Networking section which is perfect for our testing.
Doing our best to emulate a real-world performance scenario, I setup a server running Windows 2008 (x64) Server (Intel i7 965, 2GB DDR3 1600, 2x 146GB SAS drives RAID 1), a workstation running Windows Vista Ultimate x64 (Intel QX9770 4GB DDR3 1x 500GB Seagate 7200.11) and a client PC (MSI Wind U100 With built-in Intel 802.11n adapter).
The results were gathered by sending data from the Wind notebook to the server which was connected to a TRENDnet TEG-240WS and to the workstation that was connected to the TPE-S44 at different distances and determining the average transmission speed. I also had two TRENDnet TV-IP422W cameras connected using the TPE-S44 and two TPE-112GS splitters.
As usual I chose three common working points inside my house. One was in the lab within 10 feet of the DIR-655; the next was in the bedroom roughly 35 feet away and requiring the signal to travel through a wall containing the main house electrical panel and a "wet wall". The last was outside on the back porch, roughly 45 feet from the router. Both the second and third positions were out of the direct line of sight of the router.
