Hi
I have the CCR2004-1G-12S+2XS and 2 Linux rigs with backbone performance over 100gbps each. With iperf3 I get 23.5gbps when i connect the rigs directly. However when put in the Microtik on both SFP28 I only get around 10-15 gbps depending on the configuration.

Since this is far below the official specification can you please provide the exact conditions and a backup of the settings (including FW verison etc) how the official measurements were made?

My goal is to accheive a routing performance above the link speed in the following options:
1. router (ip4 only) with NAT and 5 port forewadings, WAN DHCP client, LAN DHCP server;
2. 1. but with NAT with less forewadings
3. Bridging only
4. Switching only

What of the above settings could be acheived with this router at a speed to at least 22gbps?
