If Dale would supply us with the first few lines of the following command I think it would help mark@truenas1:~ $ sysctl hw hw.machine: amd64 hw.model: Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz hw.ncpu: 4 Note that hw.ncpu isn't actually cores but rather threads. My processor has just 2 cores. I don't know how to get the CPU flags on FreeBSD nor how to determine if encryption is hardware or software based on TrueNAS. Given some time I might Google that.
