Flint 3 - WAN speed goes to 500mbit after enabling wireguard server

I had previously posted here about improving download speeds with wireguard enabled by writing “f” to /sys/class/net/interface/queues/rx-0/rps_cpus, which can be easily done in Luci by enabling LuCI → Network → Interfaces → Global Network Options → Packet Steering.

Does this recipe accomplish the same thing, or is it addressing a different problem?

Thanks for the help!
