ARGS:
delay     (float)     scanner delay multiplier, defaults to '10.0'
max_wait  (duration)  maximum wait time between operations, defaults to '15s'
cycle     (duration)  time duration between scanner cycles
```

Example: the following setting will decrease the scanner speed by a factor of 3, reducing the system resource use, but increasing the latency of updates being reflected.

```sh

// was collected since the server started, and the sum,
// average and max values across the same.
type ResourceMetric struct {
	Name   MetricName
	Labels map[string]string

	// value captured in current cycle
	Current float64

	// Used when system provides cumulative (since uptime) values
	// helps in calculating the current value by comparing the new
	// cumulative value with previous one
	Cumulative float64

	minSleep time.Duration

	// cycle will be closed
	cycle chan struct{}

	// isScanner should be set when this is used by the scanner
	// to record metrics.
	isScanner bool
}

// newDynamicSleeper
func newDynamicSleeper(factor float64, maxWait time.Duration, isScanner bool) *dynamicSleeper {
	return &dynamicSleeper{
		factor:    factor,
		cycle:     make(chan struct{}),
		maxSleep:  maxWait,

			errs = append(errs, fmt.Errorf("Unable to apply scanner config: %w", err))
		} else {
			// update dynamic scanner values.

			scannerCycle.Store(scannerCfg.Cycle)
			scannerExcessObjectVersions.Store(scannerCfg.ExcessVersions)
			scannerExcessFolders.Store(scannerCfg.ExcessFolders)
			configLogIf(ctx, scannerSleeper.Update(scannerCfg.Delay, scannerCfg.MaxWait))
		}

succeeded or failed respectively. On the destination side, a `X-Amz-Replication-Status` status of `REPLICA` indicates that the object was replicated successfully. Any replication failures are automatically re-attempted during a periodic disk scanner cycle.

To perform bi-directional replication, repeat the above process on the target site - this time setting the source bucket as the replication target. It is recommended that replication be run in a system with at least two CPU's available...

Similar to object version replication, DeleteMarker replication also cycles through `PENDING` to `COMPLETED` or `FAILED` states for the `X-Amz-Replication-Status` on the source when a delete marker is set (i.e. performing `mc rm` on an object without specifying a version).After replication syncs the delete marker on the target,...
