In 'performance' mode the CPU defaults to be throttled at 100%. If you changed hw.acpi.cpu.performance_speed to 6, then the CPU would run at 75% even with the power cord plugged in. Perhaps the best thing would be to have the bootup message display the current throttle level after saying that it is enabled? I.e., something like: acpi_cpu: CPU throttling enabled, 8 steps from 100% to 12.5% acpi_cpu: Current speed: 100% ?? -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
