Thanks for the feedback, will give it a try. I did try a Bandwidth test from one router to the other last night, from LAN interface to LAN interface I got just under a Gbps both ways which is acceptable, the CPU was under 10% which is confusing. I'm still not sure if the issue is with the firewall o...

Thanks I will try and find a way to do it, I saw a post regarding setting it up on ESXi, it helps with allowing the tx and rx to use multiple CPU's thus helping the I/O queuing.

We have a 9 core cloud core router doing 5x more traffic and the CPU usage is around 40-50% at peak. I have 2x CHR routers with 8 co...
