The Reality of File Overhead: A single 100MB file transfers significantly faster than one hundred 1MB files. This is due to the file system setup delay (e.g. SATA command queue latency, block allocation, file handle opening/closing) repeating for each file. Across slow connections, protocol encapsulation and framing overhead consume additional bandwidth, while serial protocols bypass packet-based MTU but take a constant 25% framing penalty.
