I want to build a truenas server with the cheapest CPU I can find that can support ECC RAM: Celeron G4900T + 64gb ECC RAM + 4x18 TB SAS drives.

I don’t have experience with ZFS or with truenas (core or scale), how much important is the CPU?

Use case: hundreds of thousands of small files mostly under 1 mb, but just 2-3 concurrent users

    You don’t mention your performance requirements and I’m unfamiliar with that CPU. Are you trying to saturate your 1G presumably NIC? Reads or writes?

      No, just thousands of small files. Windows takes around a minute to enumerate all the files in the main share via SMB

        That looks more like ARC problem, it can hold a large index of the filesystem if you give it enough room in ram, avoiding the need to seek thousands of files on a spinning disk, which takes time. HDDs are fine for sequential operations, Random IO, which is your usecase, is their biggest weakness.
