StarWind Software

I've just installed StarWind on a two-node Hyper-V cluster. Copy a file to the new CSV is 220 MB/s, copy from server to server over the 10 gig it's 900+ MB/s. Is there any way to fix it?

That's the wrong way to measure performance. Please check out this article to get reliable benchmarking results https://www.starwindsoftware.com/best-p ... practices/.

Also, it's a known issue: Large files in Windows Server 2019 are transferred too slow https://docs.microsoft.com/en-us/window ... e-transfer.

Thanks for the links yaroslav. Guess I'd been doing things the wrong way. Hope this will work out.

No worries. Now you know the right way to benchmark the performance of StarWind VSAN.
Let me know if there is anything else I can help you with.
