Ubuntu Blog: Optimise your ROS snap – Part 3

=> ↺ Ubuntu Blog: Optimise your ROS snap – Part 3

Welcome to Part 3 of our “optimise your ROS snap” blog series. Make sure to check Part 2. This third part is going to present safe optimisations consisting of removing duplicates and unnecessary files. We will present three different methods as well as their cumulative benefits for the performance of ROS snaps.

When snaps are bundling all their dependencies, unnecessary files are bundled too. Most dependencies are coming from APT packages. These packages are also bundling files that are not useful for our snap at runtime (documentations, build tools, etc.). All these unnecessary files count in the size of our snap and affect the “cold start”. Reducing the number of files in our snap would make it smaller and potentially start faster.

It is very difficult to gather reliable data from any tests, either with real cases or with special programs. They always give extremely variable, different, unstable values. The various caches present and the type of filesystem (btrfs, journaled, etc.), make the values very variable. It is advisable to ignore small differences (say 5-10%).

The following performance data refers to the test below (random and multiple reads/writes), trying to always maintain the same conditions and repeating three times in immediate sequence.
