| | Protocol | Performance Considerations |
| :- | :- | :- |
| `scp` | SSH (TCP) | Typically uses a single TCP connection, limited by TCP window size and RTT. Can incur higher per-byte overhead from SSH protocol framing and encryption for raw data. |
| `sftp` | SSH (TCP) | Similar to `scp` in TCP limitations, though the SFTP protocol itself can be slightly more efficient for block-based transfers. Still subject to SSH overhead. |
| `https` | TLS over HTTP (TCP/QUIC) | Benefits from modern TCP stack optimizations. HTTP/2 and HTTP/3 (QUIC) allow for efficient multiplexing and reduced latency. Optimized for large data streams. |
