You must first collect the samples using perf record. This generates an output file called perf.data.A typical CPU profile using a system profiler may involve 99 stack trace samples per second, on all CPUs. If this were a 16 CPU instance, that's 1,584 samples per second. Linux perf_events writes every sample to a perf.data file (in groups for efficiency), and usually handles this rate with low overhead.ORBIT.
