Performance optimization is the process of improving the speed, stability, and efficiency of websites, mobile applications, servers, and digital systems. Its goal is to reduce loading time, increase responsiveness, and ensure that the system remains stable even under high traffic.

Performance optimization typically includes:

• Server performance tuning

• CDN integration and caching

• Database optimization (indexing, query tuning)

• Frontend optimization (CSS JS minification, lazy loading, compression)

• Image optimization

• Load balancing and scaling

• APM monitoring tools (New Relic, Datadog, Elastic APM)

• Caching layers such as Redis

• Code level optimization

• Proper SSR CSR architecture planning

With professional performance optimization, websites load faster, user satisfaction increases, SEO results improve, and server costs decrease. Without it, systems become slow, crashes occur frequently, and conversion rates drop dramatically.
