Why There’s No Performance Impact

The MainWP Child plugin is designed to have minimal footprint on frontend performance:
  • Backend-only processing - The plugin primarily handles admin-side operations
  • No frontend scripts - No JavaScript or CSS added to public-facing pages
  • Request-based activation - Code only runs when the Dashboard communicates with the site
  • Optimized queries - Database interactions are minimized and optimized
Normal visitors to your site won’t experience any slowdown from having MainWP Child installed.
