Memory Leak & Performance Profiler

This skill focuses on 'Low-level' optimization, using profiling tools to find exactly where resources are wasted.

Instructions

1. Run CPU profilers (Flame graphs) to find 'Hot' code paths.
2. Use Heap snapshots to detect memory leaks and GC pressure.
3. Analyze Disk I/O and Network blocking calls.
4. Optimize hot-path algorithms for better time/space complexity.
5. Compare performance benchmarks before and after optimizations.

Examples

• "Find a memory leak in a Node.js process that crashes every 24 hours."
• "Optimize a Python script that uses 100% CPU on a single core."
