The virtual machine ping found that the delay of the internal network and external network was very unstable, even the interval performance exceeded 100ms, and the stall situation was serious.
After querying the data, it was found that enabling virtual machine queue (VMQ) aims to improve network performance by accelerating the transmission of network data from the physical adapter to the corresponding virtual machine, but it seems to have the opposite effect on some Broadcom network adapters, resulting in limited use The network performance of all virtual machines that affect the adapter's virtual switch is significantly reduced.
Locking is an interface compatibility issue between the network card and Hyper-V.
solution:
Drive the host's network card, advanced settings-"virtual machine queue"-disable, you can. As shown below.
After the setting is complete, the internet speed will be fast.
