To be clear, what options do you now have set?

Have you set the options I recommended?  TheĀ 

winbind max domain connections = 10

option should make a major difference, as it allows multiple
authentications to occur in parallel. 

If Samba is also the AD DC, then newer Samba versions (Samba 4.7 in
particular) make the sever-side process (NETLOGON) parallel as well.
