Magento 2 Performance Optimization

⚡ Magento 2 Performance Optimization – Speed Up Your Store

Your Magento 2 store is powerful — but without the right tweaks, it can feel like a sleepy tortoise. Let’s turn it into a turbo-charged hare! In this guide, you’ll learn how to supercharge Magento 2 performance using smart configuration and server-side optimization.

🔍 Key Optimization Areas

  • Caching – Use built-in and external cache systems
  • Indexing – Keep your indexers up to date
  • Static Content – Deploy and merge CSS/JS
  • Server Tuning – Varnish, Redis, PHP-FPM, MySQL settings

🚀 Step 1: Enable All Caches

php bin/magento cache:enable
php bin/magento cache:status

⚙️ Step 2: Set Production Mode

📦 Step 3: Merge and Minify CSS/JS

Reduce asset load with merging and minification:

  1. Go to Stores > Configuration > Advanced > Developer
  2. Set Merge JavaScript Files and Merge CSS Files to Yes
  3. Enable Minify for both

🛠️ Step 4: Use Varnish & Redis

Replace Magento’s built-in cache and session handlers with:

  • Varnish for Full Page Cache
  • Redis for session and backend cache

See our Varnish & Redis Setup tutorial for step-by-step instructions.

📇 Step 5: Keep Indexers Updated

Ensure your data is always indexed for optimal access:

php bin/magento indexer:reindex
php bin/magento indexer:status

📉 Step 6: Use Flat Catalog (Optional)

Enabling flat catalog speeds up product collection fetching:

  1. Stores > Configuration > Catalog > Catalog > Storefront
  2. Set Use Flat Catalog Category and Use Flat Catalog Product to Yes

🔧 Step 7: Tune MySQL & PHP-FPM

  • Increase innodb_buffer_pool_size in MySQL for better read/write performance
  • Use OPCache for PHP to reduce CPU usage
  • Optimize php.ini settings: memory_limit, max_execution_time

🧹 Step 8: Clean Logs & Sessions Regularly

Magento stores logs and old sessions that can slow things down:

php bin/magento log:clean
php bin/magento session:clean
