P2Lab Cache | Speed Optimization Tool

About the Extension

P2Lab Cache is an advanced caching module for Shopware 6 that significantly accelerates store performance through intelligent static content caching with dynamic loading capabilities for interactive elements.

How it works:

1. Two-tier caching system

• Server-side cache - stores complete HTML pages in your chosen backend (Redis, APCu, Filesystem)
• Browser cache - utilizes HTTP headers (ETag, Last-Modified, Cache-Control) to minimize data transfer

2. Automatic request interception

• Module intercepts HTTP requests before Shopware initializes
• If page is cached, returns it immediately (without starting the framework)
• Drastically reduces response time (from seconds to milliseconds)

3. Intelligent cache invalidation

• Tag system automatically tracks relationships between pages and products/categories
• When updating a product, automatically clears cache only for related pages
• Two invalidation modes: "request" (direct relationships only) and "extended" (related elements too)

4. Cache Warmup

• Automatic cache generation for all store pages
• Background processing via message queue system (Symfony Messenger)
• Progress monitoring and error handling

5. Dynamic content loading

• Dynamic elements (cart, user menu) are loaded asynchronously via AJAX
• Page displays instantly from cache, while personalized elements load afterwards
• User experience remains seamless, but page performs significantly faster

6. Statistics and monitoring

• Detailed cache performance statistics (hit/miss ratio, generation times)
• Cache size and compression information
• Dashboard with key metrics

7. Configurable options

• Cache backend selection (Redis for best performance, Filesystem as safe option)
• Content compression (gzcompress) for space savings
• Independent TTL settings for different page types
• Ability to disable cache for selected page types

Benefits:

• Dramatic speed improvement - pages load 10-100x faster
• Reduced server costs - lower CPU and database load
• Better SEO ranking - faster pages = higher Google rankings
• Improved conversion - fast store = more sales
