Which is it, a standalone server or a Unix domain member, it cannot be
both ;-)

This is easy, the biggest most powerful CPU possible, as much memory as
possible and the biggest HD possible ;-)

To be honest, it all depends on the number of users and just how they
are going to use the Samba machine.

The kernel has got a lot smarter and you should probably just leave it
up to it.

It might help if you could post your proposed smb.conf, we could then
point out any problems or suggest improvements.

I have removed all the default lines, but just a couple of questions
about [global]:

Why have you set the log level to 10 ? this will swamp your logfile.
Is there some reason why you have started the 'IPGAD' range at
'1' ?
The normal practise is at '10000', also using '1' means that you
should move everything from /etc/passwd and /etc/group into AD, or to
put it another way, this is a stupid range.
You are also using the winbind 'ad' backend, so have you added
anything to AD ?
Have you read this:

https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member

and this:

Interesting fact: 'public' is a synonym for 'guest ok', so you
don't
need both and the default for 'guest ok' is 'no', so you
don't really
need either.

[Samba] Fwd: Re: Ressources needed (cpus, ram, etc.) for a Samba server

Log level to 10 was for debug reasons, I can now surely set to 1 now.
Concerning idmap config IPGAD, I don't see why is the reason to start at
1...
I will set to 10000 as according to the documentation, thank you.

What do you mean by "

anything to AD ?
" ?
