@godlike I wonder what limits throughput to <200Mbps in your setup. What are the CPU utilisation you see in both cases? @dhoulbrooke do you get 400+ throughput regardless of the direction of iperf traffic flow? I assume yes since your test using two RB750r3 - one will be in opposite direction of the...
P.S. I'm wondering how could Mikrotik get 400+ Mbits on this chip, when vendor tell us: http://www.mediatek.com/en/products/connectivity/wifi/home-network/wifi-ap/mt7621na/ HW Crypto Engine 200 Mbps IPSec throughput ¯\_(ツ)_/¯ P.P.S. Hovever, I have one hypothesis. CPU of RB750Gr3 was loaded by abou...
