## Tips and Best Practices

To get realistic results, you should exercise care when running benchmarks. Here are a few tips:

### Do

* Ensure that the system executing your microbenchmarks has as little load as possible. Shutdown every process that can cause unnecessary
  runtime jitter. Watch the `Error` column in the benchmark results to see the run-to-run variance.
