Can't get 10gig speed

Hello,
I have installed router os on my lenovo hardware having Intel dual port sfp +.
I am getting bandwidth test speed around 900 mbps both direction.
I have also tested using dual port gigabit network card and bond the port to make 2gig single port by using bonding, still getting 900 mbps speed in bandwidth test.
Router os has no licence key installed yet, i was testing the speed before buying the key.

What will be the issue with the speed ? why it is capped at 900 mbps however it is connected to 10 gig port

Have you checked that autonegotiation actually went for 10G? Did you try forcing it to 10G? Have you checked CPU load during your bandwith tests?

Hello

Disabled autonegotiation solved the issue, now getting max 6.3 gig speed

Thanks

Awesome. Do check your cabling though. This might be the reason why it’s not negotiating 10G and why you’re not nearer to the actual 10G mark.
