Copilot Performance Toolkit

A practical toolkit for monitoring and potentially improving GitHub Copilot performance in large codebases. This project provides monitoring tools, workspace analysis utilities, and theoretical reasoning about AI code assistant performance.

⚠️ Important Disclaimer

This toolkit contains observations and theoretical speculation, NOT formal research. Please see DISCLAIMER.md for important information about the academic integrity of this content.

🎯 Observed Problem

Many developers experience performance issues with AI code assistants in large codebases:

• High memory usage by VS Code in large projects
• UI freezing and poor responsiveness
• Slower suggestion responses or degraded quality
• Performance issues that seem to correlate with project size

This toolkit provides tools to monitor these issues and potential approaches to address them.

🚀 Quick Start

1. Memory Monitoring

Monitor VS Code memory usage and identify Copilot performance issues:

# Basic memory monitoring
python tools/test.py --mode continuous --duration 30

# Copilot-focused analysis
python tools/test.py --copilot-focused

# Detect UI freezing
python tools/test.py --mode freeze-detection

2. Workspace Analysis

Analyze your repository and get optimized workspace suggestions:

# Analyze current directory
python tools/workspace_analyzer_enhanced.py

# Analyze specific repository
python tools/workspace_analyzer_enhanced.py /path/to/large/repo

# Dry run (analysis only)
python tools/workspace_analyzer_enhanced.py /path/to/repo --dry-run

3. Folder Comparison

Compare two folders while respecting .gitignore patterns:

python tools/compare_folders.py /path/to/folder1 /path/to/folder2

🔬 Observations and Theoretical Reasoning

Based on practical experience and computer science principles:

Common Performance Issues

• Memory usage appears to grow with project size
• Response times may slow down in larger codebases
• UI responsiveness can degrade with many files open

Theoretical Analysis

• Context management likely becomes more complex with more files
• Memory allocation for tracking file relationships may grow significantly
• Processing overhead for analyzing large project structures increases

Hypothesized Solution: Workspace Splitting

Based on theoretical reasoning, splitting large projects into smaller workspaces may help by:

• Reducing scope of files the AI needs to consider
• Lowering memory usage by limiting active context
• Improving performance through focused project boundaries

Note: These are observations and theories, not validated research findings.
