# Optimize Memory Usage

Analyze and optimize memory usage patterns to prevent leaks and improve application performance: **$ARGUMENTS**

## Instructions

1. **Memory Analysis and Profiling**
   - Profile current memory usage patterns using appropriate tools (Chrome DevTools, Node.js --inspect, Valgrind)
   - Identify memory leaks and excessive memory consumption hotspots
   - Analyze garbage collection patterns and performance impact
   - Create baseline measurements for optimization tracking
   - Document memory allocation hotspots and growth patterns over time

2. **Memory Leak Detection**
   - Set up memory leak detection for different runtime environments
   - Monitor heap snapshots and compare over time intervals
   - Track DOM node leaks in browser applications
   - Implement event listener cleanup and monitoring
   - Use profiling tools to identify growing memory patterns

3. **Garbage Collection Optimization**
   - Configure garbage collection settings for your runtime environment
   - Tune Node.js heap sizes and GC flags for optimal performance
   - Monitor GC pause times and frequency
