Measure and Optimize Rebuild Time

[abhibongale]

Measure actual rebuild times in real workflows and optimize to consistently achieve sub-2-minute rebuilds. Profile the rebuild process, identify bottlenecks, and eliminate them.

Goals

• Measure rebuild time breakdown
• Identify bottlenecks
• Optimize slow steps
• Achieve consistent < 2min rebuilds
• Document performance

Tasks

• Add timing for each rebuild step
• Identify slowest operations
• Optimize Docker build
• Optimize container restart
• Test with various code changes
• Measure final performance
• Document optimizations

Measurement

def timed_rebuild():
    times = {}
    
    start = time.time()
    build_image()
    times['build'] = time.time() - start
    
    start = time.time()
    restart_containers()
    times['restart'] = time.time() - start
    
    start = time.time()
    wait_healthy()
    times['health'] = time.time() - start
    
    return times

Acceptance Criteria

• Rebuild time < 2 minutes consistently
• 90% of rebuilds complete in < 2min
• Slowest step identified and optimized
• Performance documented
