re-queued for replication.

Replication speed depends on the cluster load, number of objects in the object store as well as storage speed. In addition, any bandwidth limits set via `mc admin bucket remote add` could also contribute to replication speed. The number of workers used for replication defaults to 100. Based on network bandwidth and system load, the number of workers used in replication can be configured using `mc admin config set alias api` to set the `replication_workers`. The prometheus...

## 1. Overview

SMB3 Multi-Channel enables the use of multiple network connections between client and server, providing increased throughput, network fault tolerance, and automatic failover capabilities. This feature aggregates bandwidth across multiple NICs and provides seamless failover when network paths fail.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 3.2.4.23**: FSCTL_QUERY_NETWORK_INTERFACE_INFO

	reports = append(reports, globalBucketMonitor.GetReport(bandwidth.SelectBuckets(buckets...)))
	consolidatedReport := bandwidth.BucketBandwidthReport{
		BucketStats: make(map[bandwidth.BucketOptions]bandwidth.Details),
	}
	for _, report := range reports {
		if report == nil || report.BucketStats == nil {
			continue
		}

On the target bucket, `s3:PutObject` event shows `X-Amz-Replication-Status` status of `REPLICA` in the metadata. Additional metrics to monitor backlog state for the purpose of bandwidth management and resource allocation are exposed via Prometheus - see <https://github.com/minio/minio/blob/master/docs/metrics/prometheus/list.md> for more details.
