Task nice Task nice CPU count CPU count CPU delay total Total CPU delay CPU run real total CPU "wall-clock" running time. On some architectures, value will adjust for cpu time stolen from the kernel in involuntary waits due to virtualization. Value is cumulative, in nanoseconds, without a corresponding count and wraps around to zero silently on overflow CPU run virtual total CPU "virtual" running time. Uses time intervals seen by the kernel i.e. no adjustment for kernel's involuntary waits due to virtualization.
