Stop losing users to slow load times

Reduce TTFB/API Response Times: Cache your routes, config, and views upfront (php artisan route:cache, config:cache) to skip disk reads on every request—this alone cuts TTFB by 50%+ for most apps. Tune PHP-FPM (worker processes, pm.max_children) and OPcache for faster code execution, and optimize DB with proper indexes on foreign keys/joins. The rationale: most Laravel slowness comes from cold starts and repeated I/O, so caching eliminates that while DB tuning targets the real bottlenecks

Best Caching for SaaS/eCommerce: Use Redis for session storage, queue jobs, and hot data (products, user profiles), with query result caching (Cache::remember() on Eloquent scopes) for lists/searches. Add full‑page HTTP caching via middleware for public pages. Why? SaaS/eCommerce have repetitive reads (catalogs, carts), so layered caching (app + HTTP) handles bursts without DB overload.

Optimize Laravel + Vue/React Bundles: Use Vite's code splitting and lazy loading for routes/components to deliver only what's needed initially, compress assets (Brotli), and serve from CDN. Preload critical JS/CSS, optimize images (WebP/AVIF), and minimize rehydration. Rationale: Core Web Vitals penalize large bundles blocking render; splitting + CDN shrinks LCP/FCP by offloading to edge networks.

Design DB Schemas/Indexes from Day One: Normalize core entities but denormalize for read‑heavy reports (e.g., order totals), always index foreign keys, composite WHERE clauses, and ORDER BY columns. Use UUIDs sparingly (prefer bigint IDs), partition large tables, and model read replicas early. The key: anticipate query patterns from business flows, not just entities—poor indexes cause 10x slowdowns that caching can't fully fix.

Scale Laravel Horizontally: Make apps stateless (Redis sessions/cache), front with load balancer (Nginx/Envoy), and distribute queues/DB reads across workers/replicas. Add auto‑scaling groups and CDN for static assets. Proven because it turns single‑node limits into cluster capacity—millions/day handled by adding cheap horizontal nodes, not vertical upgrades.
