Folks,
While waiting on my switch to get here, i run some tests and noticed the rsync transfer speed just a little bit faster over 10gb than over 1gb.
Both servers are using Chelsio 10GB 2-Port PCI-e Card PCI-E 110-1088-30, connected with a Cisco SFP-H10GB-CU1M 1 Meter Twinax 10GB Cable, both servers are using X9DRi-LN4F+/192GB, and the Chelsios are passed through to the ESXi 6.5 VMs.
1Gb NIC is on 10.10.10.0/24 and the 10Gb NIC is on 10.10.99.0/24:
iperf test run from server 1 to server 2
rsync between both through the 10Gb NICs:
dd on receiver side server:
rsync command:
Understand rsync does more than copy, so I'd expect not get 10Gb transfer, but it is the 46MB/s normal?
