My top on 7.0 says "CPU states:" not "CPU:" Are you sure you're running on 2 cores? dmesg will tell you and top will have a "C" column with 0 or 1 in it. If you're running on one core, it will explain the temperature discrepancy. > > A could of dd if=/dev/urandom etc... quickly pushes it up, but the > delta remains: > > dev.cpu.0.temperature: 51 > dev.cpu.1.temperature: 39 > > Top says: > > last pid: 1243; load averages: 0.98, 0.65, 0.48 up > 0+00:16:07 13:50:57 > 54 processes: 3 running, 51 sleeping > CPU: 0.4% user, 0.0% nice, 92.5% system, 0.0% interrupt, 7.1% idle > Mem: 22M Active, 13M Inact, 95M Wired, 1788K Cache, 15M Buf, 3797M Free > Swap: 4063M Total, 4063M Free > -- Frank Contact info: http://www.shute.org.uk/misc/contact.html _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
