On my standard make -j 8 it still gets very hot - which it never has done u= ntil very recently World and Kernel was build this afternoon - I normally rebuild every day - = kld loads Id Refs Address Size Name 1 14 0xffffffff80100000 b18a70 kernel (/boot/kernel/kernel) 2 1 0xffffffff80c19000 f5f18 zfs.ko (/boot/kernel/zfs.ko) 3 2 0xffffffffd9c0b000 1874f linux.ko (/boot/kernel/linux.ko) 4 1 0xffffffffd9c42000 346d linprocfs.ko (/boot/kernel/linprocfs.ko) 5 1 0xffffffffd9c96000 1076 daemon_saver.ko (/boot/kernel/daemon_sa= ver.ko) 6 1 0xffffffffd9c98000 729 coretemp.ko (/boot/kernel/coretemp.ko) What are the most reliable way to get idle time? Running vmstat and sysctl = dev.cpu | grep temper - seems to indicate that the grow hotter even when idle is quite high e.g. 25-50% -= but that could just be a measurement error
