TCP Poor Latency on High-Speed Networks

7/10 High

TCP/IP achieves poor round-trip latency and cannot approach the raw capabilities of next-generation high-speed networks like Myrinet and ATM. TCP was designed for wide-area networks and is not optimized for local-area or high-bandwidth, high-latency connections.

Query: “What are the most common pain points with TCP/IP for developers in 2025?”4/9/2026

While TCP/IP can achieve good throughput on currently deployed networks, its round-trip latency is usually poor. Further, observed bandwidth and round-trip latencies on next-generation network technologies such as Myrinet and ATM do not begin to approach the raw capabilities of these networks.
