Security report:
- Binary includes Java deserialization.
- Use '--enable-sbom' to assemble a Software Bill of Materials (SBOM).
--------------------------------------------------------------------------------
Recommendations:
PGO: Use Profile-Guided Optimizations ('--pgo') for improved throughput.
AWT: Use the tracing agent to collect metadata for AWT.
HEAP: Set max heap for improved and more predictable memory usage.
CPU: Enable more CPU features with '-march=native' for improved performance.
QBM: Use the quick build mode ('-Ob') to speed up builds during development.
