WARNING: the benchmark result may be unstable
* the standard deviation (10.3 ms) is 11% of the mean (96.5 ms)
Try to rerun the benchmark with more runs, values and/or loops.
Run 'python -m pyperf system tune' command to reduce the system jitter.
Use pyperf stats, pyperf dump and pyperf hist to analyze results.
Use --quiet option to hide these warnings.
