When optimizing application performance, carefully select compiler flags based on your optimization goals. For size-critical applications or accurate size measurements, use `-Oz` to prevent aggressive inlining that can distort metrics. Additionally, implement compiler caching with tools like `ccache` to significantly improve build times in development and CI environments. For CMake-based projects, enable ccache with: ``` # For direct CMake invocation cmake . -B build -G Ninja -DCMAKE_CXX_COMPILER_LAUNCHER=ccache -DCMAKE_BUILD_TYPE=Release # For npm/cmake-js projects npm config set cmake_CMAKE_CXX_COMPILER_LAUNCHER ccache ``` When analyzing binary size with tools like Bloaty, ensure you're comparing equivalent architectures by isolating specific targets: ``` # Example extracting ARM64 binary from multi-architecture framework cp MapLibre.xcframework/ios-arm64/MapLibre.framework/MapLibre MapLibre_arm64 ``` These practices ensure both efficient development cycles and optimized production artifacts.
