Routing Performance

I put the 825 through our suite of router tests, with the results shown in Table 1 along with the DIR-855 for comparison.

Table 1: Routing throughput

For all intents and purposes, the two products are the same in routing performance. I also confirmed that the 825's gigabit switch supports up to 9K jumbo frames.

Figure 8 shows a composite of WAN to LAN, LAN to WAN and simultaneous up/down IxChariot throughput tests. Throughput is nice and steady and fairly evenly balanced between upload and download. Note that I disabled the QoS Engine and SPI, which are enabled by default, to run the router tests.

The bottom line is that the 825 sits at position #3 in the current Router Charts. Along with the DIR-855, it is one of the fastest routers (for wired connections) that you can buy.
