      Trying to figure out the best way to see/retrieve not only the count of CPUs, but how they are arranged in a system.

      From what I can see/test here, I think I have a good idea, but what I really need is to see the output from a whole bunch of different setups. Especially those with multiple physical CPUs

      So if everyone could run these commands from Diagnostics > Command or the shell and copy the results here, it would help a ton, thanks!

      sysctl kern.smp.cpus; grep "SMP.*package.*core" /var/log/dmesg.boot
      

      Sample output:

      kern.smp.cpus: 2
      FreeBSD/SMP: 1 package(s) x 1 core(s) x 2 HTT threads
      

      If you have a CPU count greater than 1, but the second line doesn't show, please run:

      grep "SMP" /var/log/dmesg.boot
      

      Results so far (collected from pfSense and FreeBSD servers):

      
      kern.smp.cpus: 1 / (empty)
      kern.smp.cpus: 2 / FreeBSD/SMP: 1 package(s) x 1 core(s) x 2 HTT threads
      kern.smp.cpus: 2 / FreeBSD/SMP: 1 package(s) x 2 core(s)
      kern.smp.cpus: 2 / FreeBSD/SMP: 2 package(s) x 1 core(s)
      kern.smp.cpus: 4 / FreeBSD/SMP: 1 package(s) x 2 core(s) x 2 HTT threads
      kern.smp.cpus: 4 / FreeBSD/SMP: 1 package(s) x 2 core(s) x 2 SMT threads
      kern.smp.cpus: 4 / FreeBSD/SMP: 1 package(s) x 4 core(s)
      kern.smp.cpus: 4 / FreeBSD/SMP: 2 package(s) x 1 core(s) x 2 HTT threads
      kern.smp.cpus: 8 / FreeBSD/SMP: 2 package(s) x 4 core(s)
      kern.smp.cpus: 16 / FreeBSD/SMP: 2 package(s) x 4 core(s) x 2 SMT threads
      

      If your results are identical to ones already on the list, no need to post them. Thanks!

                    I added a summary to the initial post with results so far, if your results are identical to ones already listed, no need to report them.

                    Thanks!
