I have a problem here with extremely slow network connections from multiple VMs. Here is an excerpt translated in English: On German site someone has already taken up this issue in spring 2019 within this post. If a guest operating system under Microsoft's Hyper-V virtualization solution is set up on a host running Windows 10 (version 1709 or higher) or Windows Server 2019, the network throughput for Hyper-V guests is extremely modest. The blog reader then sent me various links with places to be found on the web, which deal with the low network throughput of Hyper-V guests on the mentioned operating system platforms.
