I'd like to purchase a server that will only run my Samba DC.? As I understand it, Samba is not very multi-threaded (?).? I expect to have around 5000 domain users.? How many cores, and how much memory would be optimal? While my second DC will be a VM, I'd prefer for at least one of my DCs to be bare metal.? Disk storage for the DC is less than 1G right now, so I know that disk won't be a problem.? I could focus on faster disk rather than larger. Thanks for any feedback, Jason.
