[Samba] Abysmal performance with Samba 4 and Windows Explorer

Sorry forgot about logs. I set log level = 0 in the smb.conf because I read
some suggestions on the internet that logging may cause issues, but that
didn't help either. What is a decent log level to get just enough debug to
analyse this problem?
I found this error message in log.smbd:

At that time I did a restart of the server (if I'm not mistaken I was
trying the max_protocol directive at that time...). There are also files in
the core directory which appear to be binary though...
Thanks!
