Magento 2 Case Studies & Real eCommerce Results
Varnish Cache Integration & Performance Boost for Magento 2
Case
The client needed to improve Magento 2 performance by enabling caching at the server level. Slow full-page rendering resulted in longer load times and reduced efficiency under load.
Solution
A full Varnish setup and integration were performed:
- Installed and configured Varnish 7.7
- Updated Apache ports and optimized listener configuration
- Enabled Magento Full Page Cache (FPC) with Varnish
- Generated and applied a custom Magento VCL file
- Ensured proper cache behavior and verified HIT/MISS response headers
Result
The updated caching layer improved performance:
- Faster full-page responses via Varnish FPC
- Better stability under heavy traffic
- Reduced load on Apache and improved server efficiency
- Faster LCP and more consistent Lighthouse metrics
Valkey Integration for Magento 2: Faster Sessions & Higher Stability
Case
Magento 2.4+ now uses Valkey as the official backend for cache and session storage.
The client needed to migrate from Redis to Valkey to ensure full compatibility with new Magento releases, improve stability, and keep their infrastructure aligned with the latest platform requirements.
Solution
A full Valkey integration was implemented:
- Installed and enabled Valkey service on AlmaLinux 8
- Updated Magento env.php configuration for sessions and cache
- Replaced legacy Redis adapters with Valkey-native settings
- Cleared caches, validated store behavior, and performed CLI-based tests
- Ensured compatibility with Magento 2.4.x+ requirements
Result
The migration ensured long-term platform stability:
- Fully compatible with Magento’s official caching backend
- Improved performance and reliability under high traffic
- Simplified maintenance thanks to stable open-source technology
- Eliminated dependency on Redis and its licensing issues
- Ready for future Magento upgrades without additional changes
Turbo Page Optimization for Magento 2
Case
The client experienced slow page load times on Magento 2, which negatively affected PageSpeed scores, user engagement, and conversion rates. Initial Lighthouse scores were low both on desktop and mobile.
Solution
A full optimization cycle was implemented, including:
- Minification & bundling of CSS/JS through Magento settings
- Custom front-end optimizations, removing heavy scripts and refactoring theme assets
- Server-level improvements, including Varnish integration and migration from Redis to Valkey
- Image and media optimization, including lazy loading and WebP
- Multiple rounds of Lighthouse and PageSpeed testing with adjustments
Result
The combined optimization steps produced significant improvements:
- Stable performance after adding Varnish + Valkey
- PageSpeed Desktop: 100
- PageSpeed Mobile: 88
- Faster TTFB and improved FCP/LCP
- Smoother UX and reduced layout shifts
