Lightning Talk: How Fast Isn’t You Constexpr? - Hossein GhahramanzadehAnigh - CppCon 2025

I investigate the compile time + run time of running an algorithm in an effort to compare how much it takes the compiler to run the same algorithm at compile time vs how much it takes to run the algorithm natively. With the findings at the end I hand roll a constexpr alternative that strikes a balance between compile-time and run-time performance.
