Hi, I have a Windows server 2012 R2 installation on a Dell R710 with an Intel AF DA nic in an x8 slot.
I also have an OmniOS installation on a Supermicro X8DTH with an Intel X520-DA2.
These devices are directly connected on a 10.10.10.0/24 subnet using Twinax. Both are configured with large packets [MTU 9014 (windows) and MTU 9000 (OmniOS)]
Performing an iperf3 (iperf -c 10.10.10.10 -i 1 -t 10) using Windows as the server:
Performing an iperf3 using OmniOS as the server:
Can someone please explain why I'm seeing considerably less than 10GB performance and why there's so much difference between using Windows and OmniOS as the sender/receiver?
Thanks in advance for any advice/suggestions!
