Summary
This episode examines a performance optimization opportunity found in Dave Plummer's 'Prime Number Sieve' comparison code. Jason identifies that a validation map used to verify prime number counts was being needlessly reconstructed on each benchmark iteration. By making a simple change to use a static const map or constexpr map instead, he demonstrates a 10% performance improvement in some compilers. The episode highlights the importance of identifying and eliminating redundant computations, especially for compile-time known data.
