If you use Samba as File Share (NAS) Samba mounts often hang by listing huge amount files like Photos.
Known Problem is the gfvs-backend is hanging up on switching between smb protocol (smb1-2-3) versions!
Faster is to use the cifs Kernel mount without the gnome-backend communication
open Terminal enter:
id myusername mkdir /home/myusername/nas/
with known id do:
Workaround edit /etc/fstab insert:
sudo nano /etc/fstab
insert at the end !!
//192.168.1XX.XXX/nas /home/myusername/nas cifs file_mode=0777,dir_mode=0777,username=myusername,password=XXXX,domain=home.local,uid=10XX 0 0
Now over 50MB’s per second should by possible over gigabit cable. If not needed disable Samba Logging!
