Next.js + Supabase Performance Optimization: From Slow to Lightning Fast

Last month, I optimized a Next.js + Supabase application that was frustratingly slow. Initial page load took 4.2 seconds, Lighthouse performance score was 62, and users were complaining.

After applying these optimization techniques, we achieved:

70% faster load times (4.2s → 1.3s)

Lighthouse score of 96 (up from 62)
