# Performance Baseline Report
**Date**: 2025-10-01
**Purpose**: Establish baseline metrics for existing Kaizen agents before BaseAgent architecture refactoring
**TODO Reference**: TODO-157, Task 0.1

---

## Executive Summary

All three existing agents measured and baselined. Performance targets mostly met, with one warning.

### Key Findings:
- ✅ ChainOfThought agent meets all targets (<100ms init, <200ms agent creation)
- ✅ ReAct agent meets all targets (<100ms init)
- ⚠️ SimpleQA agent slightly exceeds init target (133ms vs 100ms target)
- ✅ Memory usage acceptable for all agents (~36-37MB)

---

## Detailed Measurements

### 1. SimpleQA Agent
**File**: `/apps/kailash-kaizen/examples/1-single-agent/simple-qa/workflow.py`
**Lines**: 496 lines (to be reduced to 15-20 lines)

| Metric | Value | Target | Status |
|--------|-------|--------|--------|
| Import Time | 58.80ms | N/A | ✅ |
| Framework Init + Agent Creation | 133.51ms | <300ms combined | ⚠️ Framework alone: 133.3ms (target: <100ms) |
| Agent Creation Time | 0.1ms | <200ms | ✅ |
| Memory After Init | 36.31MB | <50MB | ✅ |
| Provider | Ollama | - | - |
| Model | llama3.2 | - | - |

**Performance Warning**:
```
[20:29:50.955] WARNING: Framework init time 133.3ms exceeds <100ms target
```

**Notes**:
- Framework initialization includes provider auto-detection (Ollama)
- Agent creation is extremely fast (0.1ms)
- Total initialization: 133.4ms (still reasonable)

---

### 2. ChainOfThought Agent
**File**: `/apps/kailash-kaizen/examples/1-single-agent/chain-of-thought/chain_of_thought_agent.py`
**Lines**: 442 lines (to be reduced to 25-30 lines)

| Metric | Value | Target | Status |
|--------|-------|--------|--------|
| Import Time | 37.48ms | N/A | ✅ |
| Framework Init Time | 81.51ms | <100ms | ✅ |
| Agent Creation Time | 0.06ms | <200ms | ✅ |
| Total Init + Creation | 81.65ms | <300ms | ✅ |
| Memory After Init | 36.34MB | <50MB | ✅ |
| Provider | Ollama | - | - |
| Model | llama3.2 | - | - |

**Performance Validation**:
- Framework Target Met: **True** ✅
- Agent Target Met: **True** ✅

**Notes**:
- Best performance of all three agents
- Faster import time than SimpleQA (37ms vs 59ms)
- Framework init well within <100ms target
- Transparency auto-enabled for enterprise compliance

---

### 3. KaizenReAct Agent
**File**: `/apps/kailash-kaizen/examples/1-single-agent/react-agent/workflow.py`
**Lines**: 599 lines (to be reduced to 30-35 lines)

| Metric | Value | Target | Status |
|--------|-------|--------|--------|
| Import Time | 48.50ms | N/A | ✅ |
| Framework Init + Agent Creation | 71.44ms | <300ms | ✅ |
| Memory After Init | 36.94MB | <50MB | ✅ |
| Provider | OpenAI | - | - |
| Model | gpt-4 | - | - |
| MCP Tool Discovery | 0.00s | N/A | - |

**MCP Integration**:
- Loaded 6 servers from registry
- Discovered 0 MCP servers (expected - no servers configured)
- Discovered 0 tools
- MCP discovery time: negligible impact on performance

**Notes**:
- Fastest overall initialization (71.44ms total)
- Import time faster than SimpleQA (48.5ms vs 58.8ms)
- Includes MCP tool discovery overhead
- Uses OpenAI by default (vs Ollama for others)

## Baseline for Regression Testing

### Success Criteria for BaseAgent Refactoring

The new BaseAgent architecture must meet or exceed these baselines:

**Framework Initialization**:
- **Target**: <100ms
- **Current Average**: 95.53ms
- **Acceptable Range**: 71-100ms
- **Regression Threshold**: >120ms (alert), >150ms (fail)

## Known Issues

### SimpleQA Framework Init Slowness

**Issue**: SimpleQA framework initialization takes 133.3ms, exceeding 100ms target by 33%

**Likely Causes**:
1. Provider auto-detection overhead
2. Ollama provider initialization
3. Framework config validation
4. Agent manager setup

**Expected After Refactor**:
- Lazy initialization will defer heavy operations
- Shared framework instance across agents
- Optimized provider detection
- **Target**: 71-90ms (match ReAct/ChainOfThought)

---

## Measurement Methodology

### Environment
- **Platform**: macOS (Darwin 25.0.0)
- **Python**: Python 3.x
- **Measurement Tool**: `time.time()` for elapsed time, `psutil` for memory
- **Run Configuration**: Single execution, cold start
- **Provider Config**: Auto-detected (Ollama for SimpleQA/CoT, OpenAI for ReAct)

### Metrics Captured
1. **Import Time**: Time to import agent module
2. **Framework Init Time**: Kaizen framework initialization
3. **Agent Creation Time**: Agent instance creation
4. **Total Init Time**: Framework + Agent creation combined
5. **Memory After Init**: Process RSS memory after initialization

### Measurement Code
Located in test scripts, measuring:
- `import_start = time.time()` → `import_time = (time.time() - import_start) * 1000`
- `init_start = time.time()` → `init_time = (time.time() - init_start) * 1000`
- `process.memory_info().rss / 1024 / 1024` for memory

## Next Steps

### Task 0.2: Validate Core SDK APIs
Confirm WorkflowBuilder, LocalRuntime, LLMAgentNode compatibility

### Task 0.3: Validate Kaizen Framework APIs
Confirm Kaizen.create_agent() exists and works as expected

### Phase 1: Begin BaseAgent Implementation
Use TDD approach with tdd-implementer subagent
