Hi, I have connet X552 to DLINK DXS-1210-12TC.
But that speed cannot to 10g speed.

I have try to passthrough 03:00.1 to vm(OS is ubuntu 16.04 LTS),
and I can see that ethernet card get 10g speed,
but in my host, just get 1g speed.

Any help would be greatly appreciated.
 
And I have try to upgrade ixgbe driver,
but upgrade failed.

Have you made sure the traffic is not routing over the eth0 (1Gbps)

I have the same server, and I have to try it.
When I just use eth3(10g ethernet port),
I got the same speed(1Gbps)

And the device you are testing speed to is 10Gbps?
Click to expand...

Yeah, what are you doing to test?

Personally over my intel 10gig copper interfaces, I get anywhere from 9.25Gbit/s to about 9.75Gbit/s when I test with iPerf, confirming that the interfaces are working properly.

Transferring files over NFS - however - I seem to only average about 160-200MB/s which is disappointing, especially since my ZFS pool locally on the server can read at over 800MB/s sequentially.

I feel like there is some NFS tuning I need to do.

On a side note, I have found that mii-tool always reports that the link is in 1000mbit half duplex, so I am guessing mii-tool isn't fully compatible with my Intel 10gig NIC's, as I know for a fact that is wrong, looking at the iperf output.

Also, what kind of cable are you using? I know everyone says Cat6 is OK for short runs, but in practice, I have seen some very mixed results. Cat 6a or Cat 7 is highly recommended.

I'm use ethtool to check that copper speed.
And use cat 6, maybe I'll try cat 6a or cat 7.
