Hello,
I have 3-node PVE, running on two DL380 G10 (Nodes 1 and 2) and one DL380 G9 (Node 3).
In cases where I do iperf server on node 1 and 2, and client node 3, I get full 10GBit speed, 1.10 GBytes.
If I use Node 3 as server and Node 1 or 2 as client, only getting around 700MB/s, or around 70%.
The connection to the switch-stack is LACP, so each Node has one cable to each switch, which are aggregated, and in Proxmox are also same settings with bond0 and Linux bridge.
Basically all 3 nodes...
