I am pretty new to RouterOS and Mikrotik in general. I have a new internet connection which can do P2P 1G on a Fiber. I bought a RB3011 to firewall this connection and at some point maybe also make a VPN entry to my home-network.
I have the issue, that I do not get the expected ~940Mbps (which I do get with another simple media-converter).
I also noticed that the retries-count doing an iperf3 is pretty high. Now I did two iperfs locally from my laptop to my server. The first one on the same switch-chip (both hooked up on ports ETH6-10).
Here I have a rock solid connection:

And also maybe some advice, how to improve the "only" ~600Mbps get through from SFP to ETH bridge, but CPU only at ~20%?
