samba - Apr 2019 - Ressources needed (cpus, ram, etc.) for a Samba server

Dear Samba Users,

I am preparing a Samba box as standalone server (only files server, 
centos 7).

This Samba box is a domain member server, and is dedicaded to serve 
files to about 80 domain users.

I am wondering if there are some special requirements for this purpose 
in terms of CPUs, Memory ?
The Samba box is a Vmware virtual machine, so I can easely configure this.

I noticed also in some Samba configurations, parameter socket options is 
set with TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=819
Does it worth still setting this parameter on recent linux system ?
According to the wiki https://wiki.samba.org/index.php/Performance_Tuning :
"The Samba team highly-recommends not setting the parameters described 
in this section without understanding the technical background and 
knowing the consequences. In most environments, setting these parameters 
or changing the defaults decreases the Samba network performance."

Best regards,

EdG

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.
