When using a VPS or dedicated server, network optimization is always a core factor in improving access speed and service quality. Google’s BBR congestion control algorithm, especially the latest BBR v3, performs exceptionally well in high-latency or packet-loss networks and is widely favored by technical users. However, installing and managing BBR at the kernel level is often complex, involving kernel compilation and system reboots, which discourages many users.
Now, you no longer need to worry about these technical barriers. The BBR management script developed by byJoey is designed specifically for Debian and Ubuntu systems, offering one-click installation, flexible switching of acceleration modes, and automatic kernel updates—making it a powerful VPS optimization tool.
