FVS336Gv3 - IPv6 throughput slower than IPv4

So the datasheet lists the FVS336Gv3 as having a "LAN-to-WAN Throughput" of 350mbps, with an asterisk of "Actual performance may vary depending on network traffic and environment". I am discoveri...

I know this topic is old, but I finally got a response from Netgear on my support case about this & figured I would post here. This is a confirmed hardware limitation of the device; it does not have hardware offload for IPv6 traffic. As such, there is no solution at this time. Only solution would be a new hardware design. (Kind of disappointing for a ~$225 "business" device.) As always, thanks to JohnRo and the mods for their time.

Moving on....

Hi train_wreck,

This is interesting to try however, I currently do not have an IPv6 internet connection and an FVS336Gv3 to verify this concern. May I know, what is the current firmware version of your FVS336Gv3? Kindly post image/s or screenshot/s that shows that the IPv6 connection level off around 60-65Mbps.

Firmware 4.3.3-6.

Here's a speed test from the Comcast speed test servers, using my main Ubiquiti router:

Here is the same test with the Netgear router in place; nothing else about the network changed:

I have iperf numbers measured from 2 laptops with static IPv6 addresses configured, and connected through the Netgear's WAN and LAN interfaces. Those numbers show the same kind of results: ~340mbps of transfer over IPv4, ~63mbps over IPv6.

  Hello train_wreck,
  
  I did a little search on our repository but I was not able to see further information about the IPv6 speed for the firewall. I am also thinking that it could be a hardware limitation or just a firmware issue. Please open a ticket with our Support Team, we can create a bug/issue ticket and forward it to engineering to confirm if this is a limitation or not.
  
  I look forward to your response.
  
  Thanks,
