Hello! People. Who can explain the purpose of sysctl variable kern.smp.topology? What does it affect? It may take such values: 1 -Dual core with no sharing. 2 -No topology, all cpus are equal. 3 -Dual core with shared L2. 4 -quad core, shared l3 among each package, private l2. 5 -quad core, 2 dualcore parts on each package share l2. 6 -Single-core 2xHTT 7 -quad core with a shared l3, 8 threads sharing L2. default-Default, ask the system what it wants. Does it make sense to set its value manually, if I know that my CPU Core2Duo? How to do this, select a value? I not found this explanation in any of the official guides ... Thanks!
