Hello,
I configured a Mikrotik 750Gr3 with a pppoe connection and my test speed doesn't exceed around 390-400Mbps download and upload around 350Mbps.
When I connect the cable directly (from GPON router) in my computer the test speed connection goes around 750-850 Mbps download and 650-700Mbps upload.

I changed the cable between router and pc to Cat6 same issue.

I verified the speed between 2 PCs connected on port 2 and 3 (LAN bridge) with gigabit connections, potent CPUs & RAM and ssd and the speed was around 1000Mbps (+-10Mbps).
Please can you advice me what to do next or what to try.

Thank you
Adrian

I would recommend enabling Fasttrack in the Firewall on the MikroTIk RB750Gr3 .. and u should see a big improvement.
