Wikipedia has a relatively concise explanation of CPU clock rate here: http://en.wikipedia.org/wiki/CPU_clock In intrstat's case, the CPU cycles are read from an on-chip register that advances every time the CPU clock ticks. The CPU clock ticks at the CPU clock rate, which is generally the clock rate of the processor in some unit of Hz. If this still sounds like gibberish, you might consider getting a book on Computer Architecture. "Computer Architecture: A Quantitative Approach," by John L. Hennessy and David A. Patterson is a classic. -j _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
