Optimized for maximum performance with minimal overhead:

-   **Target**: <10ms execution time
-   **Achieved**: 1-4ms actual performance
-   **Features**: Direct execution bypass, object pooling, fast cache keys
-   **Security**: Minimal (stack trace protection only)
-   **Monitoring**: Disabled for maximum speed

```typescript
const hotPath = func(criticalFunction, {
    ultraFast: "minimal",
    memoize: true,
    cacheTTL: 300000,
});
```

#### Standard Mode (Default)

Balanced performance and functionality for typical production use:

-   **Target**: <50ms execution time
-   **Features**: Smart caching, performance tracking, audit logging
-   **Security**: Stack trace protection, basic monitoring
-   **Monitoring**: Essential metrics enabled

```typescript
const businessLogic = func(regularFunction, {
    // Uses optimized defaults
    memoize: true,
    smartCaching: true,
    auditLog: true,
});
```

#### Secure Mode

Maximum security and comprehensive monitoring:

-   **Target**: <200ms execution time
-   **Features**: Full encryption, detailed metrics, threat detection
-   **Security**: Complete security suite enabled

```

### API Reference

#### Core Methods

##### `execute(...args): Promise<R>`

Executes the wrapped function with all configured security and monitoring features.

##### `getStats(): FunctionStats`

Returns comprehensive execution statistics including performance metrics and cache statistics.

##### `getCacheStats(): CacheStats`

Returns detailed cache performance information including hit rates and memory usage.

##### `clearCache(): void`

Clears all cached results and resets cache statistics.

##### `destroy(): void`

Properly cleans up all resources, active executions, and event listeners.

#### Advanced Methods

##### `getOptimizationSuggestions(): OptimizationSuggestion[]`

Returns AI-generated suggestions for improving function performance based on execution patterns.

##### `getPerformanceTrends(): PerformanceTrend[]`

Returns historical performance data for trend analysis and capacity planning.

##### `warmCache(): void`

Pre-populates cache with frequently accessed data for improved response times.

### Best Practices

#### Choosing Performance Modes

**Use Ultra-Fast Mode When:**

-   Function is called frequently (>1000 times/minute)
-   Response time is critical (<10ms requirement)
-   Security requirements are minimal
-   Function handles non-sensitive data

**Use Standard Mode When:**

-   Balanced performance and security needed
-   Function handles business logic
-   Debugging capabilities required
-   Moderate call frequency (<100 times/minute)

**Use Secure Mode When:**

-   Function processes sensitive data
-   Compliance requirements exist
-   Comprehensive audit trails needed
-   Security is prioritized over performance

#### Performance Optimization Guidelines

1. **Enable Caching**: Always enable `memoize` for functions with deterministic outputs
2. **Tune Cache TTL**: Set appropriate `cacheTTL` based on data freshness requirements
3. **Monitor Metrics**: Use `performanceTracking` to identify bottlenecks
4. **Optimize Hot Paths**: Apply `ultraFast: 'minimal'` to frequently called functions
5. **Memory Management**: Configure `maxMemoryUsage` based on available system resources

#### Security Considerations

1. **Encryption**: Enable `autoEncrypt` for functions handling PII or sensitive data
2. **Audit Logging**: Always enable `auditLog` in production environments
3. **Stack Protection**: Keep `stackTraceProtection` enabled to prevent information leakage
4. **Threat Detection**: Enable in high-security environments with `threatDetection`

### Migration Guide

#### From Version 1.x

```typescript
// Old approach
const wrappedFunction = fortify(myFunction, {
    cache: true,
    security: "high",
});

// New approach
const wrappedFunction = func(myFunction, {
    memoize: true,
    autoEncrypt: true,
    auditLog: true,
});
```

#### Performance Migration

For existing high-performance requirements:

```typescript
// Replace performance-critical functions
const optimizedFunction = func(existingFunction, {
    ultraFast: "minimal", // New ultra-fast mode
    memoize: true,
    cacheTTL: 300000,
});
```

### Advanced Usage

#### Custom Cache Strategies

```typescript
const customCachedFunction = func(expensiveOperation, {
    smartCaching: true,
    cacheStrategy: "adaptive",
    maxCacheSize: 5000,
    cacheTTL: 600000, // 10 minutes
});
```

#### Comprehensive Monitoring

```typescript
const monitoredFunction = func(businessCriticalFunction, {
    auditLog: true,
    performanceTracking: true,
    detailedMetrics: true,
    anomalyDetection: true,
});

// Access monitoring data
const stats = monitoredFunction.getStats();
const trends = monitoredFunction.getPerformanceTrends();
const suggestions = monitoredFunction.getOptimizationSuggestions();
```

#### Event Handling

```typescript
const eventAwareFunction = func(myFunction, options);

eventAwareFunction.on("execution_success", (data) => {
    console.log(`Function executed successfully in ${data.executionTime}ms`);
});

eventAwareFunction.on("cache_hit", (data) => {
    console.log(`Cache hit for execution ${data.executionId}`);
});

eventAwareFunction.on("performance_warning", (data) => {
    console.warn(`Performance degradation detected: ${data.message}`);
});
```
