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

    As Lawrence said: “It’s not ram intensive, it’s ram efficient.”
    It doesn’t let ram sit there unused. So you only really need 1G of ram per 1T of storage in general, outside some very rare cases. But the more ram you throw at it, the more snappy it becomes, but there are some diminishing returns. For example, 128G of ram on a 20T array won’t be fully utilized most of the time.
    L2Arc raises ram requirements, because you also need to store it’s index there.
