In what file system to store the data of the virtual game server?

Question

VMware

Help me decide on the file system for the virtual machine for better performance, on which the game server under windows7 will be installed .
I tested RAW and QEMU , it seems that QEMU is more productive, although the forums write the opposite.
I raise the server using Proxmox :

There is also a question about the cache, advise:

Answer 1

How did you test the speed of the disk?
Rather, it turned out that you tested the speed of working with the cache. Test with the No cache
RAW option faster, as the system is working directly with the disk.
As for the cache, depending on what you need speed, or data safety. Much faster would be Write back . Safer No cache.
I have several windows machines on virtual machines, with write back, for a couple of years there were no failures.
