### Memory Patterns

```bash
# Store performance baseline
npx claude-flow@alpha memory store \
  --key "performance/baseline/timestamp" \
  --value "$(date -Iseconds)"

npx claude-flow@alpha memory store \
  --key "performance/baseline/metrics" \
  --value '{
    "throughput": 145.2,
    "latency": 38.5,
    "utilization": 0.78,
    "errorRate": 0.012,
    "timestamp": "'$(date -Iseconds)'"
  }'
```

## Phase 2: Profile System

### Objective

### Scripts

```bash
# Profile swarm execution
npx claude-flow@alpha performance profile-swarm \
  --duration 300 \
  --sample-rate 100 \
  --output swarm-profile.json

# Profile individual agents
for AGENT in $(npx claude-flow@alpha agent list --format json | jq -r '.[].id'); do
  npx claude-flow@alpha performance profile-agent \
    --agent-id "$AGENT" \
    --duration 60 \
    --output "profiles/agent-$AGENT.json"
done

# Profile memory usage
npx claude-flow@alpha memory profile \
  --show-hotspots \
  --show-leaks \
  --output memory-profile.json

# Profile network communication
npx claude-flow@alpha performance profile-network \
  --show-latency \
  --show-bandwidth \

```

## Phase 3: Analyze Issues

npx claude-flow@alpha performance analyze \
  --input swarm-profile.json \
  --detect-bottlenecks \
  --detect-memory-leaks \
  --detect-deadlocks \
  --output analysis-results.json

# Identify bottlenecks by type
npx claude-flow@alpha performance bottlenecks \

```

## Phase 5: Validate Results

### Objective

  --duration 300 \
  --output optimized-metrics.json

# Run comparison benchmark
npx claude-flow@alpha benchmark run \
  --type swarm \
  --iterations 10 \
  --output optimized-benchmark.json

# Compare before/after
npx claude-flow@alpha performance compare \
  --baseline baseline-metrics.json \
  --current optimized-metrics.json \
  --output improvement-report.json

# Calculate improvements
THROUGHPUT_IMPROVEMENT=$(jq '.improvements.throughput.percentage' improvement-report.json)
LATENCY_IMPROVEMENT=$(jq '.improvements.latency.percentage' improvement-report.json)

echo "Throughput improved by: $THROUGHPUT_IMPROVEMENT%"
echo "Latency improved by: $LATENCY_IMPROVEMENT%"

# Validate improvements meet targets
npx claude-flow@alpha performance validate \
  --improvements improvement-report.json \
  --targets performance-targets.json

# Generate final report
npx claude-flow@alpha performance report \
  --type comprehensive \
  --include-baseline \
  --include-analysis \
  --include-optimizations \
  --include-results \
  --output final-performance-report.md

# Archive performance data

```

### Validation Criteria

**Minimum Improvements:**
- Throughput: +15%
- Latency: -20%
- Resource utilization: More balanced (variance <10%)
- Error rate: -50% or <1%

**Validation Checks:**
```bash
# Check if improvements meet targets
if (( $(echo "$THROUGHPUT_IMPROVEMENT >= 15" | bc -l) )); then
  echo "✓ Throughput target met"
else
  echo "✗ Throughput target not met"
fi

if (( $(echo "$LATENCY_IMPROVEMENT >= 20" | bc -l) )); then
  echo "✓ Latency target met"
else
  echo "✗ Latency target not met"
fi
```

## Success Criteria

- [ ] Baseline established
- [ ] System profiled
- [ ] Issues identified and categorized
- [ ] Optimizations applied
- [ ] Improvements validated

### Performance Targets
- Throughput improvement: ≥15%
- Latency reduction: ≥20%
- Resource utilization variance: <10%
- Error rate: <1%
- Optimization overhead: <5%

## Best Practices

1. **Baseline First:** Always establish baseline before optimizing
2. **Measure Everything:** Comprehensive metrics collection
3. **Identify Bottlenecks:** Focus on critical path
4. **Incremental Optimization:** Apply optimizations incrementally
5. **Validate Improvements:** Always measure after optimizing
6. **Document Changes:** Record all optimization actions
7. **Regression Testing:** Ensure optimizations don't break functionality
8. **Continuous Monitoring:** Track performance over time

## Common Issues & Solutions

### Issue: No Performance Improvement
**Symptoms:** Metrics unchanged after optimization
**Solution:** Re-analyze bottlenecks, verify optimizations applied correctly

### Issue: Performance Regression
**Symptoms:** Performance worse after optimization
**Solution:** Rollback changes, re-evaluate optimization strategy

### Issue: Inconsistent Results
**Symptoms:** Performance varies significantly between runs
**Solution:** Increase measurement duration, check for external factors
