Just comming back to this today, will do a side by side compare of the dmesg later to make sure that they *are* identical as claimed, but the idea of disabling half the CPU's is an excellent one! Aha, brilliant idea! > Check dmesg for the APIC numbers corresponding to the CPUs you want to > disable and add the corresponding entries to /boot/loader.conf, e.g.: You mean this bit? FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu2 (AP): APIC ID: 2 cpu3 (AP): APIC ID: 3 cpu4 (AP): APIC ID: 4 cpu5 (AP): APIC ID: 5 cpu6 (AP): APIC ID: 6 cpu7 (AP): APIC ID: 7 > hint.lapic.1.disable="1" > hint.lapic.3.disable="1" > hint.lapic.5.disable="1" > hint.lapic.7.disable="1" gives me... hint.lapic.1.disable="1" hint.lapic.3.disable="3" hint.lapic.5.disable="5" hint.lapic.7.disable="7" rebooting now to give it a try... -pete. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
