RB4011 - Shockingly poor IPv6 performance

Thu Jul 25, 2019 9:18 pm

Is it normal for the IPv6 performance to be so poor on this device?

With IPv4 the device easily gets 9Gbps+ in forwarding performance at about 60% CPU. With IPv6 it can only achieve 1.6Gbps with the CPU almost maxed out.

Yes: there is no stack optimisation (=fasttrack) for ipv6
