EoIP + IPSec RB750Gr3 problems at 50% load

Wed Jun 30, 2021 6:47 pm

Hello,
I had to expand my public network over two DCs. so I have created site-to-site EoIP IPSec connection between them.
At around 70Mbps (added IN + OUT) on EoIP tunnel I am getting problems packet drops. Yet RB750Gr3 is only 50% loaded at the time. Is there any way to improve it's performance or at least use full potential?
There is almost no firewall, only input to protect unathorized access.
At the other end there is CCR1036 which is totally bored at the time, load 1-4% tops.

Looks like one core is running at 100%. The RB750Gr3 have 2 cores and 4 threads.
Guess this is single threaded so it would explain the drops.
Also verify that you run hardware offload.
CCR and RB750Gr3 does not support all the same things for hardware offload.

I use to have this router and it could push more with IPSec then 70 Mbit.
