iperf3 results between Chelsio T6225-CR and Intel X710-DA4
I ran two iperf3 tests between two hosts using Chelsio T6225-CR and Intel X710-DA4, respectively. Both NICs are connected to the supervisor interfaces on a Sup8E in a Cisco Catalyst 4500E chassis. Wirespeed is 10 Gbit/s.
This was done on host.A.FQDN which has the Chelsio T6225-CR NIC and runs FreeBSD/amd64 stable/12 r348730:
