\fBCPU\fP Linux CPU (logical processor) number. Yes, it is okay that on many systems the CPUs are not listed in numerical order -- for efficiency reasons, turbostat runs in topology order, so HT siblings appear together.
\fBAVG_MHz\fP number of cycles executed divided by time elapsed.
-\fB%Busy\fP percent of the interval that the CPU retired instructions, aka. % of time in "C0" state.
+\fBBusy%\fP percent of the interval that the CPU retired instructions, aka. % of time in "C0" state.
\fBBzy_MHz\fP average clock rate while the CPU was busy (in "c0" state).
\fBTSC_MHz\fP average MHz that the TSC ran during the entire interval.
