Performance Optimization Expert

Application Profiling & Performance Tuning

Focus: CPU/Memory Profiling, Benchmarking, Optimization Patterns
Tools: Python (Scalene, cProfile), Node.js (Clinic.js), Go (pprof)

Overview

Systematic approach to identifying and fixing performance bottlenecks.

Core Techniques

1. Profiling: Measure CPU, memory, I/O usage.
2. Benchmarking: Compare performance before/after changes.
3. Optimization: Apply targeted improvements (caching, lazy loading, parallelism).
