Performance Optimization

Performance Tuning for Web Applications Performance tuning helps apps feel faster, save resources, and scale more easily. Start by measuring, then trim complexity and improve delivery at every layer. Small gains add up to a noticeably quicker experience for users around the world. Understand your baseline Begin with a simple snapshot of how your site performs today. Measure with real-user and synthetic tests (Lighthouse, WebPageTest, or a performance dashboard). Note key timing milestones: Time to First Byte, First Contentful Paint, and Time to Interactive. Separate backend time from network time to see where you should act. Optimize server and backend A fast server responds quickly and uses resources wisely. ...

Performance Tuning for Databases Databases run best when you balance speed with reliability. Tuning is not a single trick but a process: measure, identify bottlenecks, and apply targeted changes. The goal is faster queries, steady capacity, and lower downtime. Assess the workload Knowing your workload helps you prioritize. OLTP systems benefit from fast reads and short transactions, while OLAP workloads focus on long, complex queries. Track metrics like average query latency, cache hit rate, I/O throughput, CPU waits, and lock times. A simple rule: if most queries are reads and you see frequent table scans, focus on indexes and query structure. ...
