How I reduced website load time by 60%
Just finished a major performance optimization project and the results are incredible! 🚀 What I did: 1. Implemented lazy loading for images and components 2. Set up code splitting with React.lazy() 3. Moved static assets to a CDN 4. Optimized database queries (added proper indexes) 5. Enabled Brotli compression 6. Reduced bundle size by removing unused dependencies Before: 4.2s load time After: 1.7s load time The biggest win was the CDN - cut image load time by 70% alone. Would love to hear what techniques have worked for you!
Database optimization techniques that actually work
Database running slow? Here's my go-to checklist: Query Optimization: - Add indexes on frequently queried columns - Use EXPLAIN ANALYZE to find bottlenecks - Avoid SELECT *, only get what you need - Use prepared statements Infrastructure: - Connection pooling (pgBouncer for Postgres) - Read replicas for heavy read workloads - Redis/Memcached for caching - Partition large tables Monitoring: - Track slow queries - Monitor connection pool usage - Set up alerts for unusual patterns Last week I found a missing index that was causing 5-second queries. Added the index, now it's 50ms. What's your go-to optimization technique?
