Open source community achieved 2gbps routing speed on many routers with mt7621. Is there any plans for doing this on mt7621 based mikrotik routers (hex for example)? https://forum.openwrt.org/t/2-gbps-wan- ... ces/131478

I assume you mean 1gbps full duplex, this is lumped together as a total throughput for up and down, looking at the block diagram there are two gigabit full duplex connections to the CPU, not four or more?! With a firewall of around 60 rules and fasttrack running I get around 1200-1300mb/ps total due to cpu limit which is 100% loaded.
