## 📈 Performance Tuning

### Container Optimization
```bash
# Adjust worker processes (in gunicorn_config.py)
workers = (2 × CPU_cores) + 1

# Database connection pool
pool_size = 10
pool_recycle = 3600
```

### Monitoring Setup
```bash
# Health check endpoint
curl http://localhost:5003/health

# Container logs
podman logs mold_cost_tool

# Database performance
podman exec mold_cost_db psql -U postgres -c "SELECT * FROM pg_stat_activity;"
```

## 🚨 Troubleshooting

### Common Issues

**Container won't start:**
```bash
# Check logs
podman logs mold_cost_tool

# Check port conflicts
netstat -tulpn | grep :5003

# Verify environment
podman exec mold_cost_tool env | grep POSTGRES
```

**Database connection failed:**
```bash
# Check database container
podman exec mold_cost_db pg_isready -U postgres

# Verify database exists
podman exec mold_cost_db psql -U postgres -l
```

**Application errors:**
```bash
# Check application logs
podman logs mold_cost_tool

# Test database connection
podman exec mold_cost_tool flask shell
```
