I'm done manually tuning DDS parameters!

Raise your hand if this sounds familiar:

  1. You just want better latency or higher throughput for your ROS2 app — but DDS throws hundreds of parameters at you and you have no idea where to start.
  2. So you end up spending hours (or days) manually tweaking, re-running benchmarks, and tweaking again… only to end up with “good enough” instead of actually good.

If that’s you, I have something that might help: GitHub - qualcomm-qrb-ros/ROS2-DDSConfig-Optimizer: An AI-driven tool that automatically tunes DDS configuration for ROS2 applications. · GitHub

It’s an AI-driven tool that automatically tunes FastDDS configuration for your ROS 2 application. All you need to provide is:

  1. Your performance targets — latency, throughput, reliability, CPU/memory limits, whatever matters to you — in a simple XML file
  2. An initial DDS config as the baseline

That’s it. You’ll get back the best DDS configuration tailored to your application. :sparkles:

Would love to hear your feedback, bug reports, or feature ideas — issues and PRs are very welcome!

Nice, but the time spent setting performance targets could be the same as tuning the DDS.

Thanks for you comments.

Setting a performance target is a lot easier than tuning the DDS config. If you’d rather not go through the process of setting performance targets over and over again, you can just start with the toughest target you have in mind, and it’ll automatically give you the DDS config that gets as close to that target as possible.

Alright, thank you, I will give it a try !
