How to Use Linux Server TCP BBR for Congestion Control

In this episode of Linux Server Admin with Fexingo, Lucas and Luna dive into TCP BBR congestion control—a Google-developed algorithm that can dramatically boost network throughput and reduce latency. They explain how BBR works at a high level, compare it to traditional algorithms like CUBIC, and walk through the practical steps to enable it on a Linux server: checking the kernel version, loading the tcp_bbr module, and setting the congestion control via sysctl. They also discuss real-world use cases like streaming servers and CDNs, and note potential pitfalls with firewall or bufferbloat scenarios. By the end, you'll understand why BBR has become a go-to for performance-sensitive workloads and how to test it yourself.
