Performance - more
Subjectively, I found the menus of the FVS336G to be quite responsive. As I was evaluating the menus and options of the FVS336G, I periodically logged into an FVX538 and RVL200 for comparison purposes. Menu responsiveness on the FVS336G seemed quicker than the FVX538 and equal to the RVL200.
Figure 15 shows stable routing throughput at nearly 60 Mbps both downstream and upstream. This means the router may not be able fully utilize its gigabit WAN port capability, but the lack of peaks and valleys in the graph indicates consistent performance and throughput.

I am also impressed with the FVS336G's solid 3DES throughput of 15-17 Mbps in Figure 16. In comparison, NETGEAR’s FVX538 3DES throughput maxed out under 13 Mbps, in spite of its additional 3DES Encryption Accelerator. The Linksys' RV042 does provide superior 3DES throughput at 22-32 Mbps, though.

Figure 17 displays SSL throughput at ~11Mbps in both directions. Considering that most remote users utilizing an SSL VPN connection will be over links with significantly less throughput, this is certainly adequate performance.
