Output Format

## Performance Testing Plan: [System Name]

### Testing Overview
- **System Type:** [Web/Mobile/API/Desktop Application]
- **Performance Goals:** [Response time/Throughput/Concurrency]
- **Test Environment:** [Hardware configuration/Network environment]

### Performance Testing Strategy

#### Test Types
| Test Type | Test Objective | Key Metrics | Execution Priority |
|-----------|----------------|-------------|-------------------|
| Load Testing | Performance under normal load | Response time, Throughput | P0 |
| Stress Testing | Performance under extreme load | Maximum concurrency | P1 |
| Spike Testing | Sudden traffic handling | System stability | P1 |

#### Performance Requirements
- **Response Time:** 
  - Page loading: ≤ 3 seconds
  - API response: ≤ 500ms
  - Database query: ≤ 200ms
- **Throughput:** ≥ 1000 TPS
- **Concurrent Users:** ≥ 500 users
- **Resource Usage:** CPU ≤ 80%, Memory ≤ 85%

### Test Scenario Design

#### Scenario 1: Normal Load Testing
- **User Count:** [Concurrent user count]
- **Duration:** [Test duration]
- **Business Operations:** 
  1. [User login - 20%]
  2. [Browse products - 40%]
  3. [Place orders - 30%]
  4. [Logout - 10%]

#### Scenario 2: Stress Testing
- **Stress Strategy:** Gradually increase load to system limit
- **Monitoring Focus:** System crash point, recovery capability
- **Failure Criteria:** Response time > 10 seconds or error rate > 5%

#### Scenario 3: Spike Testing
- **Spike Simulation:** Large number of users accessing in short time
- **Test Duration:** 15-30 minutes peak period
- **Focus Metrics:** System stability, recovery time

### Test Execution Plan

#### Test Environment Preparation
- **Hardware Configuration:** [Server configuration requirements]
- **Network Environment:** [Bandwidth requirements]
- **Monitoring Tools:** [Performance monitoring tool configuration]

#### Test Data Preparation
- **User Data:** [Test user accounts]
- **Business Data:** [Product, order data]
- **Base Data:** [System configuration data]

#### Execution Steps
1. **Baseline Testing:** Single user performance baseline
2. **Load Testing:** Performance verification under normal load
3. **Stress Testing:** Performance testing under extreme load
4. **Stability Testing:** Long-term running stability

### Monitoring and Analysis

#### Key Monitoring Metrics
- **Application Layer:** Response time, throughput, error rate
- **System Layer:** CPU, memory, disk, network
- **Database:** Connection count, query time, lock wait

#### Performance Bottleneck Analysis
- **Frontend Performance:** Page loading, resource optimization
- **Backend Performance:** Interface response, database queries
- **System Performance:** Server resources, network bandwidth

### Test Report
- **Performance metrics achievement**
- **Performance bottleneck identification**
- **Optimization recommendations**
- **Risk assessment**
