🌊 Tsunami V3

Advanced BBRv3 kernel module with aggressive parameters.

Warning

Ensure that your kernel has support for BBRv3 (consider using the XanMod Kernel).

Support Linux kernels version 6.10+.

Use of this kernel module is at your own risk.

Installation

1. Ensure that your Linux kernel meets the requirements and install the necessary programs (git, dkms, etc.).

2. Clone repository.

   sudo git clone https://github.com/Zhousiru/tsunami-v3.git /usr/src/tsunami-v3

3. Build and install kernel module.

   sudo dkms add tsunami/v3
   sudo dkms build tsunami/v3
   sudo dkms install tsunami/v3

4. Load tcp_tsunami kernel module and switch net.ipv4.tcp_congestion_control to tsunami.
