Meeting C++ 2026 - The Performance Mindset

Mathieu Ropert

On Day 3 at 9:00 (CET/Berlin) in Track E [Bernstein Room and online]

Software performance doesn't happen on accident, nor can it be an afterthought. Through my career I have found that with the right combination of factors most non-trivial codebases can achieve significant performance improvements.

I will illustrate this idea through the story of a 2x performance patch I made for a game as a side project by explaining not just what was done, but more importantly how and why it was possible to achieve in the first place.

While we will show some code and explain how it was made faster, this talk will put a strong emphasis on a wider spectrum such as profiling, learning, planning, curiosity and personal motivation.
