I done reload of ixgbe with MQ=0,0 and RSS=1,1
There are no luck with speed.

One other thing that separates the 82574 and the 82599 is that 82599 is
a multiqueue interface. Try loading the driver with RSS=1,1 to see if
this issue might somehow be related to multiqueue.
Other than that the only other thing I can think of would be to start
rate limiting the ixgbe port itsel
One important thing that i not writed from start - this is real
internet, so this is not a LAN, but WAN
I have average 27 ms latency beetween hosts.

Based on the info you provided I would say one possible red flag would
be the flow control bits in the statistics. Specifically:

I got one issue, and seems i need help from driver developers.
I have a some servers located in a different datacenters around
Russia, we used mostly 82575/827576 intel nic managed by e1000e and
igb drivers. When i testing speed with iperf from one 82576 card to
another - all working good, i
