I have a Windows 10 Pro host with a PCIE Gigabit NIC, running a Windows Server 2019 guest in VMWare Workstation Pro 15.5.7 (Build 17171714). I also have Comcast/Xfinity 400 Mbps internet.
Using Google Speedtest:
The host machine clocks 400-450 Mbps downstream and 10-12 Mbps upstream.
The guest machine clocks only 100-150 Mbps downstream and struggles to reach 10 Mbps upstream.
I've Googled this, and while I found similar situations, the only applicable solution I came up with was changing the virtual ethernet card to "e1000" or "vmxnet3" in the *.vmx file, but it was already set to "e1000e" and changing it made it worse (–50 Mbps or totally broken, respectively). Most solutions seemed to be specific to some sort of VMWare cloud/cluster implementation that I don't have.
The guest OS reports the hardware as an "Intel 82574L Gigabit Network Connection" (Driver 12.15.22.6), but doing a speedtest in Google seems to suggest it's not living up to its nomenclature.
Is there anything to be done for this?
