Don't worry about your CPU. All modern CPUs (Athlon 64, Pentium 4, Core 2, ...) can enter power-saving features, which lowers their speed automatically when idle.
If you put some heavy task on tham, they will run full-speed. There are utilities that can measure speed accurately (under Windows) in Real-Time, but I don't know such utilities under Linux. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
