This counter counts additional I/O fragments the MSCP server had to issue beyond the original requests, typically because a transfer had to be broken into smaller pieces. A high fragment count suggests inefficiency in how requests are being serviced, which can add overhead and slow down the effective throughput this node delivers to remote requesters. For example, if remote nodes issue unusually large or oddly-aligned transfer requests, this node's server may need to split them into extra fragments, inflating this counter.
