Investigating the Ceph / 40G stuff a bit more.
Iperf3 from my workstation to cluster node 3 (the first one I put the connectx in) gets 24.7 Gbps with 13.7K retries with workstation sending to the node, and only 13.5 with 57948 in the reverse direction.
I'm beginning to wonder if PCIe bandwidth is part of the issue.
