Cannot get the full 10 Gigabits

[mbekh]

As the title suggests, cannot get to the full 10 Gigabit speed only caping around 6-6,5 Gigabits. Weird thing is that when transferring files FROM the server can get closer to the 7Gigabits but to the server closer to 6. Both server and the windows machine running intel's X540.

 Also Hex Os shows my Lan port as 5 gig.

Are there maybe some settings I'm missing?

Here's the screenshot running OpenSpeed test

I have the same issue. HexOs shows my 10 gbe NIC as 5 gbe.

What about the speed you get?

I can’t test this right now. I have to upgrade my switch to 10 gbe first.

i can confirm that in hex its reading 10gig nic as 5gig  as this network card come out of old server which was running truenas and was reading as 10gig
