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) and the client PC was an ASUS G2S -X1 With built-in Intel 802.11n adapter. The results were gathered by sending data from the ASUS notebook to the server at different distances with the built in adapter and a TP-Link TL-WN821N average transmission speeds were recorded for each.
We compared the ASUS RT-N15 against the D-Link DIR-655 set to allow n and g connections only. All wireless tests were completed with WPA2 Personal (with the AES cipher, as it has been proven to provide better performance). The router was placed in the exact same position as well as the notebook at its various testing locations for fair comparison.
- Connection Speed
I was rather impressed with the listed connection speeds of the ASUS RT-N15; on both adapters with n and g enabled I was able to connect at 144Mbps which was faster than the 130Mbps I saw with the D-Link DIR-655. Range was also very good considering the lack of the normal antenna. With only n enabled I was able to reach 300Mbps connection speed on both adapters.
As usual, to test the speed of the RT-N15 I chose three common working points inside my house. One was in the lab within 10 feet of the routers; 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.

The ASUS RT-N15 was able to keep up with the D-Link DIR-655, even without any visible antennas.
Gaming performance and router latency is always going to be something to think about when picking out a high-speed router. The ASUS RT-N15 has got you covered there. In both of our latency tests the RT-N15 showed it is more than capable of meeting your gaming needs and also was able to keep a low ping score for normal traffic.

Our latency / gaming tests were performed with ASUS' Gaming Blaster enabled. Gaming was on a Counter Strike Source server with more than half of the available slots in use.
