I am going to build an small 4 disks NAS server with FreeNAS/ZFS. I've read that due to ZFS performance 8GB is the recommended amount of RAM for the solution, but I wonder about the CPU. Currently I am considering Celeron G1610T, 2.3GHz as low cost alternative and Xeon E3-1220LV2, 2,3GHz on the other end.
Is choosing the Celeron CPU going to hurt performance somehow? I am not planning to run VMs nor other applications, just a backup solution.
