Taking into account the cluster specification you mentioned, StarWind is not the bottleneck as the network configuration might be. For the similar setup of StarWind HyperConverged Appliances, we install, at least, 25 GbE network adapters and switches, however, 40 GbE would be preferable. I believe you should benchmark the network performance, whether 10 GbE network is the bottleneck or not for your environment.
As it was emphasized, use Live Optics to get current performance utilization picture by your production. Additionally, you might use diskspd to benchmark storage performance and network utilization.
Please tag or dm me should you have any questions.
Have a nice day!
