Object Pooling Pattern
Reuse objects instead of allocation:
- Pre-allocate object pools
- Reuse deactivated objects
- Avoid frequent new/delete calls
- Reduce garbage collection overhead
Memory Arenas
Allocate large memory blocks:
- Custom allocators for specific types
- Bump pointer allocation
- Clear entire arena at once
- Faster than individual allocations
Stack vs Heap
- Stack: Fast, automatic cleanup
- Heap: Flexible size, manual management
- Prefer stack when possible
- Use smart pointers for heap
Smart Pointers
- unique_ptr: Exclusive ownership
- shared_ptr: Reference counting
- Automatic memory cleanup
- Prevent memory leaks
Conclusion
Efficient C++ memory management through object pooling, custom allocators, and smart pointers minimizes garbage collection overhead and maximizes game performance.
