📄 Description

CGO_CFLAGS and CGO_CXXFLAGS were being set without optimization flags, which overrides Go's default -O2 and results in unoptimized C++ code.

This caused performance degradation in release builds compared to local go build which uses the default optimization.

  • build_darwin.sh: add -O3 to CGO_CFLAGS and CGO_CXXFLAGS exports
  • Dockerfile: preserve CGO_CFLAGS/CGO_CXXFLAGS from build args instead of overwriting them
  • app/README.md: update documentation to include -O3
