## 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.

func sftpLogOnceIf(ctx context.Context, err error, id string, errKind ...any) {
	logger.LogOnceIf(ctx, "sftp", err, id, errKind...)
}

func shutdownLogIf(ctx context.Context, err error, errKind ...any) {
	logger.LogIf(ctx, "shutdown", err, errKind...)
}

func stsLogIf(ctx context.Context, err error, errKind ...any) {
	logger.LogIf(ctx, "sts", err, errKind...)
}

func tierLogIf(ctx context.Context, err error, errKind ...any) {

    protected void doStart() {
      notifyStarted();
    }

    @Override
    protected void doStop() {
      notifyStopped();
    }
  }

   * A NoOp service that will delay the startup and shutdown notification for a configurable amount
   * of time.

    private final long delay;

    NoOpDelayedService(long delay) {
      this.delay = delay;

    socketFactory[proxyServer2] = server2.socketAddress

    println("\n\nRequest to ${server2.socketAddress}")
    executeSynchronously(request)
      .apply {
        // We may have a single failed request if not clean shutdown
        if (cleanClose) {
          assertSuccessful()
          assertCode(200)

          assertThat(server2.requestCount).isEqualTo(1)
        } else {

     * that once the Thread returns to the Executor that this Executor composes, the interruption
     * will still be present. If the composed Executor is an ExecutorService, it can respond to
     * shutdown() by returning tasks queued on that Thread after {@link #worker} drains the queue.
