10 Magento 2 Performance Optimisation Tips for 100/100 PageSpeed

Achieving a 100/100 PageSpeed score with Magento 2 might seem impossible, but with the right optimisations, it's absolutely achievable. Here are my top 10 tips based on real-world implementations.

1. Implement Full Page Cache (FPC)

Full Page Cache is your first line of defense against slow page loads. Configure Varnish properly:

bin/magento config:set system/full_page_cache/caching_application 2
bin/magento setup:config:set --http-cache-hosts=varnish

2. Optimize Images with WebP

Convert all product images to WebP format for 30% smaller file sizes:

• Use Magento's built-in image optimisation
• Implement lazy loading for below-the-fold images
• Set proper image dimensions to prevent layout shift

3. Consider Hyvä Themes

Hyvä Themes is a game-changer for Magento performance:

• 90% less JavaScript compared to Luma
• Alpine.js instead of Knockout.js and jQuery
• Tailwind CSS for minimal CSS footprint
• Native 100/100 PageSpeed scores out of the box

4. Database Optimisation

Regular database maintenance is crucial:

• Clean log tables regularly
• Optimize flat catalog tables
• Use Redis for session storage
• Enable query caching

5. Enable Production Mode

Always run production stores in production mode:

bin/magento deploy:mode:set production

6. Configure Redis Caching

Redis significantly improves cache performance:

'cache' => [
    'frontend' => [
        'default' => [
            'backend' => 'Cm_Cache_Backend_Redis',
            'backend_options' => [
                'server' => '127.0.0.1',
                'port' => '6379',
                'database' => '0'
            ]
        ],
        'page_cache' => [
            'backend' => 'Cm_Cache_Backend_Redis',
            'backend_options' => [
                'server' => '127.0.0.1',
                'port' => '6379',
                'database' => '1'
            ]
        ]
    ]
]

7. Optimize CSS Delivery

• Inline critical CSS for above-the-fold content
• Defer non-critical styles
• Remove unused CSS
• Minimize CSS files in production

8. Implement CDN

Use a CDN for static content delivery:

• CloudFlare for global distribution
• Configure proper cache headers
• Implement image optimisation at CDN level
• Enable HTTP/2 and Brotli compression

9. Elasticsearch Configuration

Optimize search performance:

• Use Elasticsearch 7.x or higher
• Configure proper index settings
• Implement search result caching
• Optimize synonym and stopword configuration

10. Regular Performance Monitoring

Continuous monitoring identifies bottlenecks:

• Use New Relic or Blackfire for profiling
• Monitor slow queries with MySQL slow query log
• Track Core Web Vitals
• Set up automated PageSpeed tests

Results You Can Expect

After implementing these optimisations, you can expect:

• 90+ PageSpeed scores on mobile
• 100/100 scores on desktop
• 50% reduction in server response time
• Improved Core Web Vitals
• Better search engine rankings
• Higher conversion rates
