Short feedback:
Just for the test I have checked the 10GBit network performance
between two FreeBSD 13.0 servers (both HP DL380g7 machines)
transfering data in both directions

The ssh performance using 10GBit network connection on FreeBSD 13.0
is approx 7 times higher than the one on OpenBSD 6.4.
Is it the question of the "ix" NIC driver of OpenBSD 6.4?
(X520-DA2 NICs from Intel)
Does one of you achieve good 10Gbit network performance with other
10Gbit NICs?
Thank you in advance for your hints.
Kind regards
Mark

Hi,
Please allow me few questions regarding 10GBit network performance on
OpenBSD 6.4.
I face quite low network performance for the Intell X520-DA2 10GBit
network card.
Test configuration in OpenBSD-Linux-10GBit_net_performance.txt -

Compare to Linux the 10GBit transfer from/to OpenBSD is few times slower:

The scp transfer rate is like 21MBytes/s only per ssh connection
(OpenBSD <-> Linux):

The 1GBit cooper based NIC works also slower but reaching almost 40%
of the max trasfer rate of 1 Gbit:

Thank you in advance for your hints what OpenBSD 6.4 settings do I miss.
Best regards
