# Local LLM Performance Testing Plan

## Overview
This document outlines a comprehensive testing framework to compare the performance and quality of different local hosted LLMs on coding tasks. The framework will measure both speed and quality metrics to provide actionable insights for model selection and optimization.

## Objectives
- Evaluate response time and throughput of different LLMs
- Assess code quality and correctness of generated outputs
- Measure resource utilization during code generation
- Provide standardized comparison between different models
- Enable reproducible testing environments

## Key Metrics to Measure

### Performance Metrics
1. **Response Time**: Time from request to first token
2. **Tokens Per Second (TPS)**: Generation speed
3. **Total Latency**: Complete generation time
4. **Resource Usage**: 
   - CPU utilization
   - Memory consumption
   - GPU utilization (for GPU-enabled models)
   - VRAM usage (for GPU-enabled models)

### Quality Metrics
1. **Code Syntax Accuracy**: Valid syntax according to language rules
2. **Functional Correctness**: Code produces expected outputs
3. **Code Efficiency**: Algorithmic efficiency and best practices
4. **Code Readability**: Code structure and documentation
5. **Task Completion Rate**: Properly solving the given coding challenge

## Testing Framework Architecture

## Integration Points

### Existing Tools
- Local LLM APIs (e.g., text-generation-webui)
- Python-based LLM libraries
- System monitoring tools (htop, nvidia-smi)
- Code linting and validation tools

### Data Storage
