Unable to find how to update the Network speed in Windows

Question

I want to understand where the value of Network speed is found in Windows and the options to change it.

I am using the Windows Sysinternals bginfo, which generates desktop backgrounds that include important information about the system. https://learn.microsoft.com/en-us/sysinternals/downloads/bginfo

It shows me that the Network Speed is 4GB.

I do not doubt that it is correct. I have see the performance during busy times and it never goes over 3.4GB.

The closest thing I can think of is Link speed

Get-NetAdapter is showing that the NIC speed is set to 10Gbps.

C:\Windows\System32>wmic NIC where NetEnabled=true get Name,Speed
Name                      Speed
vmxnet3 Ethernet Adapter  10000000000

PS C:\Users\xxxxx> Get-NetAdapter

Name                      InterfaceDescription                    ifIndex Status       MacAddress             LinkSpeed
----                      --------------------                    ------- ------       ----------             --------- Ethernet0                 vmxnet3 Ethernet Adapter                      5 Up           xx-xx-xx-xx-xx-xx        10 Gbps

Get-NetAdapterHardwareInfo shows the speed in GT/s, which is Gigatransfers per second. 1 GT/s is 8 times bigger than a GB/s

There are no QoS rules set on the Windows machine.

Running Get-NetQosPolicy showed nothing.

It is a virtual machine, Esxi 7.0U3, on a VMware environment. The underlying vmnics look fine.

There do not appear to be any setting caps:
