performanceMonitor: PerformanceMonitor = ...

Global performance monitor instance

Shared instance for application-wide performance tracking. Use this for convenience when you don't need isolated monitoring.

#### Example

    import { performanceMonitor } from './utils/performance.js';

    // Record duration
    performanceMonitor.recordDuration('api_call', 150);

    // Get statistics
    const stats = performanceMonitor.getStats('api_call');
