Routing Performance

I tested routing performance using our standard router tests. All tests were done with the SPI firewall disabled, client in DMZ and a new setting called "NAT Filtering" set to "Open" in order to try to get the IxChariot tests to complete. But even with all this, the LAN to WAN tests would run, but not finish.

This doesn't mean that there is anything wrong with the 834B, since it's common for IxChariot to have problems with testing through SPI+NAT firewalls. I was still able to get usable throughput readings, which are found in Table 1 below.

Test Description Throughput
Total Simultaneous
Maximum Simultaneous Connections 128
Firmware Version
Table 1: Routing performance

Since the total simultaneous throughput is less than 100 Mbps, it looks like the 834B's Broadcom-based processor is matched to the limitations of the product's 10/100 Ethernet ports. One bright spot, however, is that the 834B's 128 simultaneous connections put the 854T's 72 to shame.

Figure 8 shows what the throughput variation looks like on the simultaneous routing test. It looks pretty well behaved, although with significant variation on long continuous transfers.
