I hope answering in English is OK - my German is nicht so gut.
This thread is about VMware performance of a Linux Host. The solution was NOT to use NTFS filesystem for the VM computer location. That solves the problem of utter slowness (if working at all). This was relevant since Ubuntu 18.04 LTS times (not 16.04 LTS or before) until the Linux kernel at that time - not tested with latest kernels (which are said to have new NTFS drivers).
As for bad performance on Windows - maybe a reason for a new thread. As such, I would expect the problem being with the configuration of the VM computer or possibly missing resources of the Host. The most likely candidate is the memory allocation (too little for the VM, too much for the VM in terms of Host RAM, too little RAM on the Host (not likely since you see similar things on a server where you probably have enough RAM), awful disk performance (= old HDD), too little resources available for you actual VM task (= your system is busy doing something else), missing Windows Updates (there are many things that screw up Windows performance), 3rd party antivirus software which is blocking the decent use of VM disk files (= try without, or change the config). And then there are bunch of other reasons.
If you want to discuss with me, link the question to me - I'm not actively following this Forum.
