Routing Performance
I put the 855 through our suite of router tests, with the results shown in Table 1 along with the DGL-4500 for comparison.

Table 1: Routing throughput
The speedier Ubicom IP5170 processor results in an additional 100 Mbps of routing throughput over the DGL-4500's. Remember that my Maximum Simultaneous Connection test is limited to a maximum of 200 connections.
Figure 7 shows a composite of WAN to LAN, LAN to WAN and simultaneous up/down IxChariot throughput tests. Throughput is nice and steady and evenly balanced between upload and download. Note that I disabled the QoS Engine and SPI to run the router tests.
