Here are some ways Magento can improve website speed when migrated and optimized properly:
- Built-in caching - Magento has robust built-in caching for blocks, pages and full page caching to significantly speed up load times.
- CDN support - Easy integration of CDNs like Varnish can massively improve performance by caching assets.
- Image optimization - Magento can resize, compress and lazy load images to reduce page weight.
- Minification and bundling - CSS/JS files can be minified and bundled to reduce HTTP requests.
- Async/deferred JS loading - Improves page render time by loading JS asynchronously.
- Indexing and cron management - Proper indexing and cron setup ensures optimal performance.
- Server optimization - Tweaking PHP settings, using a caching server like Redis, appropriate managed hosting goes a long way.
- Code optimization - Follow Magento best practices for minimal, optimized code to enhance performance.
- Frontend performance tools - Leverage tools like New Relic or Blackfire to locate and fix bottlenecks.
With the right optimization techniques, Magento can actually improve the speed and performance compared to less optimized systems. The key is planning performance from the start.
