Some time ago I blogged about a strange CPU/Thread problem which affected various NAV versions (2013-2016) in virtual environments;
This especially affected VMWare machines, specifically running the vmxnet3 network-adapter.
I recently got some info, that this is also a general issue of Windows with this adapter!
Changing some settings of the network-adapter seem to help, stabilizing the system and boosting performance!
