# Monitor extraction performance
with monitor.timer("metadata_extraction"):
    async for work_unit in source.get_workunits():
        # Process work unit
        pass

# Get performance metrics
metrics = monitor.get_metrics("metadata_extraction")
print(f"Average time: {metrics.get_average_time():.2f}s")
print(f"Total calls: {metrics.call_count}")
