This is available in /proc/cpuinfo and expressed in MHz. 1MHz is 1 million cycles per second. However, you have to be careful with CPU clock speed throttling, i.e., varying clock frequency based on utilization. To avoid problems, you need to lock the speed by forcing the min/max frequencies via sysfs. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ perfmon2-devel mailing list perfmon2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/perfmon2-devel
