How do I optimize small object allocations for game development?

// Example of Object Pooling in C++
#include 
#include 
#include 

class GameObject {
public:
    GameObject() { std::cout << "GameObject created\n"; }
    ~GameObject() { std::cout << "GameObject destroyed\n"; }
};

class ObjectPool {
public:
    ObjectPool(size_t size) {
        for (size_t i = 0; i < size; ++i) {
            pool.push_back(std::make_unique());
        }
    }

    std::unique_ptr acquire() {
        if (!pool.empty()) {
            auto obj = std::move(pool.back());
            pool.pop_back();
            return obj;
        }
        return nullptr; // No objects available
    }

    void release(std::unique_ptr obj) {
        pool.push_back(std::move(obj));
    }

private:
    std::vector<:unique_ptr>> pool;
};

int main() {
    ObjectPool myPool(10); // Create a pool of 10 GameObjects
    auto obj1 = myPool.acquire(); // Acquire an object from the pool
    myPool.release(std::move(obj1)); // Release the object back to the pool

    return 0;
}
