This is a story of how I used a few readily-available Open Source tools to achieve huge optimizations in zbus, a pure Rust D-Bus library. This was long journey but gains were worth the efforts. I will go through each single bottleneck found, how it was found and why it was a bottleneck and how it was optimized away. While attending this talk will by no means make you an expert in optimizations, it is my hope that by you will be able to relate to some of bottlenecks or solutions I will present ("
