Carsten has a different approach for testing RDMA functionality. More visual, UI and it stresses the system more to the max you might even get to full line speed. He will live migrate a VM using SMB via RDMA whilst watching the performance monitor counters. A must do & see.

figures to understandable stuff: use Windows Calc > select Data (Windows 10/11). there is a decent converter of bytes to any other format like GBit or such.
See increased amounts customers where for some reason the RDMA counter disappear in WAC performance monitor (cluster and node), but they are still accessible in perfmon. Do you have found any fix for that? I believe this is reproducible if you use disable-NetadapterRDMA / enable-netadapterRDMA once on the node. Anyone else, solutions?
secondly: I have found a reference on the internet that RDMA cannot be activated on a ManagementOS VMNetworkAdapter on SET switch, even though it is one THE features of SET to support RDMA. Currently on Azure Stack HCI 22H2 (August 2023), even if the physical adapters are correctly configured and the SET switch and virtual adapter has SR-IOV functions available, it is not possible to make RDMA work on the virtual adapter (get-netadapterRDMA result is RDMA enabled, operational false).
