Hello.
I have very bad network performance on Hyper-V (Windows Server 2019 Standard) external virtual switch. File transfer speed from Virtual machine to physical machine is about 40MB/s, while file transfer from Hyper-V host to same physical machine is aobut 120 MB/s. Server is new, Proliant DL 380 Gen10. 1 physical network card is for management and other three are in Nic Teaming connected to external virtual switch. I've already tried to use without network teaming and speed is still slow. I read about some problems using VMQ and Broadcom network cards(HPE Ethernet 1Gb 4-port 331i Adapter), but this problem was known few years ago. SR-IOV is not enabled, because ethernet card does not support it. Driver release is latest. All suggestions to fix my problem are welcome.
Regards,
Marko
