NAT64 and performance

How does NAT64 compare to typical NAT44 in terms of speed for 500Mbit+ lines, for say MIPS devices?Is it more demanding or not,assuming the router in question is not also the one doing the typical NAT 44?

Hi @user5077

from my point of view, it must demand more CPU cycles because translating v6->v4 and vice versa could not be done in L3 offloading (SW or HW) because protocol is changed at mid point
