Hi ijdemes,
Responding to an older message of yours:
I am runnning vSphere 6.7 U1, VMware Tools 10338, vmxnet3 driver version 1.8.3.1.
I'm on 6.5U2, VMware Tools 10.2.1, and vmxnet3 1.7.3.7. That is, where vmxnet3 is used, it's 1.7.3.7 – I just noticed that my file server and one of the VMs are using E1000e adapters, and hence Intel drivers. Can't imagine that affecting SMB behavior as that's a few OSI layers up, but I'll change the config and will upgrade VMware Tools. I'll stick with 6.5U2, though
