I'm running into a really strange issue, if I do a fresh reboot of my Host computer my networking works great. As soon as I start a virtual machine however I get really poor netoworking performance on my Host until I reboot my Host computer.  Running wireshark I'm seeing a lot of `TCP Out-Of-Order` and `TCP Dup ACK` packets that only show up after launching a VM for that first time. This issue persists until I reboot, and happens whether I have and VMs running or not.  Any thoughts? Or ways to troubleshoot? I'm running: 16.1.0 build-17198959 I have a few VMware network adaptors I have configured, one for each of the NIC's on my Host machine.

Alright so it was pretty difficult to troubleshoot, but updating VMware tools inside the VM seems to have fixed the issue. I dont know why performance got so bad in windows server when it was totally fine in my other VM's with the old version of vmware tools but it appears to be ok now.

Is there a way I can check on the Hyper-V integration? Im not sure If I ever explicitly installed it or not on my host.

I updated to 16.1 yesterday, now the performance in my Windows Server 2019 VM is extremely bad, its very very sluggish and the VM can barely run. My other Windows 10 VMs work great as well as my linux VMs. Should I just roll back the patch?  I have 64GB of host memory and an i9-10900k - so there should be plenty of system resources available (and the VM worked great before the patch). I saw there was now a VM config option for Server 2019, I switched from Server 2016 to the new option, but it didnt make any difference for my performance problem.    I also tried setting: bcdedit.exe /set hypervisorlaunchtype off  It didn't make a difference either.
