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, (2x Xeon Quad Core 3.0 GHz 1333MHz FSB, 4GB DDR2 FB-DIMMS, 2x 146GB SAS drives in RAID 1) as well as setting up a NAS (Thecus 5200 Pro) that was capable of Link Aggregation and Jumbo Frames. Since the TEG-240WS covers a larger network than our usual networking devices, I wanted to add in a few more clients rather than our usual single client run.
1 - HTPC system Windows Vista Ultimate on an Intel E7200, 4GB RAM connected through a powerline connection.
1 - Wireless system an ASUS G2S-X1running Windows Vista Ultimate x64, using n-Spec wireless connected through a D-Link DIR-655 in AP mode with WAP-2 PSK AES.
1 - Hard wired system Core i7 965, 6GB Kingston RAM, Windows Vista Ultimate x64.
I ran Performance Test 6.1 on each as well as file transfers (3GB ISO file) and streamed HD (1080p) to each in Media Center.
The TEG-240WS was compared to a standard D-Link DGS-2208, granted the 2208 is not an enterprise class switch but it serves to demonstrate the advantages of a switch like the TEG-240WS over a less expensive model. The following advanced features were enabled on the TEG-240WS:
Trunking (for the Thecus 5200 Pro)
*signal travelling through wet wall and main house electrical panel
Overall, the TEG-240WS saw an impressive improvement in all traffic types. Even the limited powerline connection experienced a boost.
For my file transfers I found that over a wired system I was able to move my test file to the 5200 Pro in 1 minute and 39 seconds with the TEG-240WS and with trunking and jumbo frames this was in stark contrast to the 3 minutes and 20 seconds it took with the 2208. For transfers from the 5200 Pro my times were around 2 minutes and 13 seconds for hardwired systems versus over 4 minutes on the 2208.
For Wireless my times were -
TEG-240WS - 6:50 Up 9:50 Down
DGS-2208 - 10:12 Up 12:35 Down
For PowerLine -
TEG-240WS - 6:45 Up 9:40 Down
DGS-2208 - 10:15 Up 13:01 Down
HD Video streamed from the 5200 Pro was flawless on all media; there were no stutters, clicks or other anomalies. In addition, streaming the HD Video to the HTPC systems was not affected by other internet traffic.
