There is some information in the docs at Tranquil IT: 
https://samba.tranquil.it/doc/en/samba_fundamentals/samba_server_dimensionning.html
<https://samba.tranquil.it/doc/en/samba_fundamentals/samba_server_dimensionning.html#dimensioning-the-memory>

They have experience with (very) large environments.

Dear Kees,

Thank you for the information and for the link to Tranquil IT?s site. We
had already reviewed that documentation, and while it?s helpful in
understanding Samba4 server sizing, our inquiry is slightly more specific.

What we need to know is if there are defined limits in Samba4 regarding the
maximum number of users, computers, and objects that it can efficiently
handle in a production environment. We understand that these limits may
vary depending on server resources (memory, CPU, I/O speed), but we?re
looking for concrete information on whether there are any inherent
restrictions within Samba4 itself, particularly in infrastructures with
more than 20,000 users and over 100,000 total objects.

Any additional experience or reference on these specific limits would be
greatly beneficial, as we are in the process of planning the scalability of
our infrastructure and want to ensure we avoid long-term performance issues.

Thank you in advance for any further insights you can provide.

Kind regards,
Gabriel
