Do *not* use the MinIO Grid for:

* Large payloads.

Only a single connection is ever made between two servers.
Likely this means that this connection will not be able to saturate network bandwidth.
Therefore, using this for large payloads will likely be slower than using a separate connection,
and other connections will be blocked while the large payload is being sent.

## Handlers & Routes

	if globalServerCtxt.JSON {
		return fmt.Sprintf("You are running an older version of MinIO released %s, update: %s", newerThan, downloadURL)
	}

	// Return the nicely colored and formatted update message.
	return colorizeUpdateMessage(downloadURL, newerThan)
}

// colorizeUpdateMessage - inspired from Yeoman project npm package https://github.com/yeoman/update-notifier

	// metacacheSharePrefix controls whether prefixes on dirty paths are always shared.
	// This will make `test/a` and `test/b` share listings if they are concurrent.
	// Enabling this will make cache sharing more likely and cause less IO,
	// but may cause additional latency to some calls.
	metacacheSharePrefix = false

//go:generate msgp -file $GOFILE -unexported

// metacache contains a tracked cache entry.
