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, (Core i7 965 12GB DDR3 1333 2x 147GB 15k RPM SAS HDDs) which was connected directly to the TPE-80WS. The client PCs were a HTPC system running over a 100Mb Powerline adapter, a Dell Latitude D930 With built-in Intel 802.11n adapter (which connected to a D-Link DIR-655) and single desktop system running directly into the TPE-80WS . The results were gathered by sending data from the client PCs to the server and determining the average transmission speed.
When you have a switch in your network its sole purpose is to keep your traffic flowing. With the TPE-80WS we have 16GB of switching power to help us maintain a high-traffic level. On the other side we were also able to hook up a NAS device with 802.3ad Link Aggregation as well as the rest of our test systems and two PoE devices (2x TRENDnet TV-IP422W using TPE 112GS PoE Splitters).
As you can see, the TPE-80WS is a very healthy switch. It handles multiple speed traffic and PoE functions without missing a beat.
The proper support for 802.3ad means that my NAS can push out 2GB of bandwidth for multimedia requests. Even 1080p HD video seems snappier on the TPE-80W. Working on my HTPC I saw the video library screens pop up faster as the Media Center inside Windows 7 was able to access the available files much quicker.
When the TPE-80WS was connected to the TEG-240WS using RSTP, my overall network speed improved when dealing with HD and SD video served over the network. This was due to being able to run my Thecus N5200 Pro NAS using 802.3ad on the TPE-80WS and allowing the RSTP to fix the topology between the switches properly. I was also able to trunk the connection between the two switches to allow for faster transfer between the two.
