Ah, fair enough. (I have Windows 10 Home myself, which has neither!)
Well, @elche99 , if you’re concerned about network speed, the first thing I would try is setting up a kernel mount to the SMB share.
Have a read of this: Mounting network shares with autofs (alternative to fstab)
I suggest you try not using a credentials file the first time you set it up, it’s slightly less fiddly.
Once you’ve successfully mounted the SMB share, you can then add a Kodi source for the root filing system, which points to the mounted folder. That will give you better performance than a Kodi-level NFS source.
