Native Performance - Mesin Balap Formula 1

Pengantar: Mesin Balap yang Dioptimalkan untuk Kecepatan Maksimal

Bayangkan Native Performance sebagai mesin balap Formula 1 yang dirancang khusus untuk mencapai performa maksimal di sirkuit tertentu. Setiap komponen dioptimalkan hingga detail terkecil - dari aerodinamika yang mengurangi drag, mesin yang disetel untuk power-to-weight ratio optimal, hingga ban yang dipilih khusus untuk kondisi track. Tidak ada komponen yang berlebihan, semuanya berfokus pada satu tujuan: kecepatan dan efisiensi maksimal.

Native Performance adalah kemampuan aplikasi untuk berjalan dengan performa optimal pada platform target dengan memanfaatkan secara langsung capabilities hardware dan operating system. Berbeda dengan abstraction layers yang menambah overhead, native performance memberikan akses direct ke system resources untuk mencapai throughput maksimal dengan [[Latency]] minimal. Ini berkaitan erat dengan [[Performance Optimization]], [[Threading]], [[Memory Management]], dan [[Zero-Copy]] operations.

Mengapa Native Performance Krusial?

• User Experience: 60 FPS smooth animations dan instant response
• Battery Efficiency: Optimal resource usage untuk longer device life
• Competitive Advantage: Faster apps win user preference dan retention
• System Integration: Deep integration dengan platform-specific features

CPU Performance Techniques:

// SIMD Optimization - Parallel Processing
#include <immintrin.h>

// Scalar version - satu operasi per waktu
void add_arrays_scalar(float* a, float* b, float* result, int size) {
    for (int i = 0; i < size; i++) {
        result[i] = a[i] + b[i];
    }
}

// SIMD version - 8 operasi paralel (AVX)
void add_arrays_simd(float* a, float* b, float* result, int size) {
    int simd_size = size - (size % 8);
    
    for (int i = 0; i < simd_size; i += 8) {
        __m256 va = _mm256_load_ps(&a[i]);
        __m256 vb = _mm256_load_ps(&b[i]);
        __m256 vresult = _mm256_add_ps(va, vb);
        _mm256_store_ps(&result[i], vresult);
    }
    
    // Handle remaining elements
    for (int i = simd_size; i < size; i++) {
        result[i] = a[i] + b[i];
    }
}

// Cache-friendly data access
struct Point3D {
    float x, y, z;
};

// ❌ Bad: Array of Structures (AoS) - cache misses
Point3D points[1000];
for (int i = 0; i < 1000; i++) {
    points[i].x *= 2.0f; // Loads entire struct, uses only x
}

// ✅ Good: Structure of Arrays (SoA) - cache friendly
struct Points3D {
    float x[1000];
    float y[1000]; 
    float z[1000];
};

Points3D points;
for (int i = 0; i < 1000; i++) {
    points.x[i] *= 2.0f; // Sequential memory access
}

Memory Management - Sistem Bahan Bakar Efisien

Memory management seperti sistem bahan bakar Formula 1 yang harus memberikan power maksimal sambil meminimalkan weight dan consumption.

// Custom Memory Allocator untuk Performance
class PoolAllocator {
private:
    void* memory_pool;
    size_t pool_size;
    size_t block_size;
    std::vector<void*> free_blocks;
    
public:
    PoolAllocator(size_t pool_size, size_t block_size) 
        : pool_size(pool_size), block_size(block_size) {
        
        memory_pool = aligned_alloc(64, pool_size); // 64-byte aligned
        
        // Initialize free block list
        char* ptr = static_cast<char*>(memory_pool);
        for (size_t i = 0; i < pool_size; i += block_size) {
            free_blocks.push_back(ptr + i);
        }
    }
    
    void* allocate() {
        if (free_blocks.empty()) {
            return nullptr; // Pool exhausted
        }
        
        void* block = free_blocks.back();
        free_blocks.pop_back();
        return block;
    }
    
    void deallocate(void* ptr) {
        free_blocks.push_back(ptr);
    }
    
    ~PoolAllocator() {
        free(memory_pool);
    }
};

// Object pooling untuk menghindari allocation overhead
template<typename T>
class ObjectPool {
private:
    std::queue<std::unique_ptr<T>> pool;
    
public:
    std::unique_ptr<T> acquire() {
        if (pool.empty()) {
            return std::make_unique<T>();
        }
        
        auto obj = std::move(pool.front());
        pool.pop();
        return obj;
    }
    
    void release(std::unique_ptr<T> obj) {
        obj->reset(); // Reset object state
        pool.push(std::move(obj));
    }
};
