WARNING: the benchmark result may be unstable
* the standard deviation (1.37 us) is 13% of the mean (10.5 us)

Try to rerun the benchmark with more runs, values and/or loops.
Run 'python3 -m perf system tune' command to reduce the system jitter.
Use perf stats, perf dump and perf hist to analyze results.
Use --quiet option to hide these warnings.
