Magento Performance Optimization: A Complete Guide
Speed Matters
Every 100ms of page load time costs you 1% in conversions. For a store doing $1M/year, that is $10,000 per 100ms of delay.
Full Page Cache
Configure Varnish as your full page cache. This alone can reduce TTFB from 2-3 seconds to under 100ms for cached pages.
Database Optimization
Regular index maintenance, query optimization, and proper use of flat tables can dramatically improve catalog performance.
Image Optimization
Use next-gen formats (WebP, AVIF), implement lazy loading, and serve images through a CDN. Images typically account for 60-80% of page weight.
Redis for Sessions and Cache
Move session storage and cache to Redis. This eliminates filesystem I/O bottlenecks and improves cache hit rates.
