Routing Performance

The results of our suite of router tests are shown in Table 1.

Test Description Throughput - (Mbps)
Total Simultaneous
Maximum Simultaneous Connections 190
Firmware Version
Table 1: Routing test results

The results show that the 6504n is plenty fast for any ISP connection. And the high number of Simultaneous connections means that it should be fine for BitTorrent and gaming use, too.

Use the Router Charts to see how the 6504n stacks up against other routers.

Figure 6 shows a composite of WAN to LAN, LAN to WAN and simultaneous up/down IxChariot throughput tests. I'm not sure what is causing the high throughput variation when I run up and downlink separately. Note that the QoS feature was disabled for these tests.

Figure 6: Throughput test results

Speaking of QoS, I thought I'd see how close the router came to the programmed limits and how smooth the throughput was. I've seen some routers with similar bandwidth-limiting QoS that appeared to limit throughput by using an on/off technique and controlling the duty cycle—not a very sophisticated technique!

Figure 7: QoS test throughput

Figure 7 shows the IxChariot throughput when I programmed a 0.5 Mbps uplink (LAN > WAN) bandwidth limit and a 1.0 Mbps downlink (WAN > LAN) limit. Throughput looks nice and smooth with the actual values around 8% lower than the programmed value. Close enough for me!
