Hello,
I have a 2 node Hyper-V cluster running on Windows Server 2022. Both devices are directly connected to each other. Their specs are:
Dell R740XD
2x Xeon Gold 6134
384 GB of ram
PERC H730P
Mellanox Connect-X4 25G
MTU has been set to 9014. However, I am seeing replication barely go above ~1.5G on the dedicated replication interface. I temporarily allowed Starwind to utilize the 10G interfaces on these servers as well, and I am seeing equal performance on those as I am on the 25G interfaces.
I'm running the latest Mellanox drivers, and multi-threaded iperf tests should 9~15 Gbit, the CPU is barely taxed typically idling at ~10%. What can I do to improve replication speed?
