Magento 2 Performance Optimization: From 8 Seconds to 0.8 Seconds

# The Problem

A client's Magento 2 store was loading in 8+ seconds, causing a 70% cart abandonment rate. Here's how we reduced it to under 1 second.

## Step 1: Enable Redis for Cache and Sessions

Redis is the single biggest performance improvement you can make.

## Step 2: Configure Varnish

Full-page caching with Varnish can serve pages 10x faster.

## Step 3: Database Optimization

Run the Magento indexer, optimize slow queries, and add missing indexes.

## Step 4: Image Optimization

Enable WebP images, lazy loading, and CDN delivery.

## Results

- Page load: 8s → 0.8s (90% improvement)
- Core Web Vitals: All green
- Conversion rate: +35%
