## 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%]
- **Monitoring Metrics:** [Response time, TPS, error rate, resource usage]

#### Scenario 2: Stress Testing
- **Test Objective:** Find system performance limits
- **Load Growth:** [Gradually increase load until system crashes]
- **Key Metrics:** [Maximum concurrency, crash point, recovery time]

### Test Execution Plan

#### Test Phases
1. **Baseline Testing:** Establish performance baseline
2. **Load Testing:** Verify target load performance
3. **Stress Testing:** Detect system limits
4. **Stability Testing:** Long-term running verification

#### Test Tools
- **Load Tools:** [JMeter/LoadRunner/Gatling]
- **Monitoring Tools:** [APM tools/System monitoring]
- **Analysis Tools:** [Performance analysis tools]

### Performance Bottleneck Analysis

#### Common Bottlenecks
- **Application Layer:** [Code logic, algorithm efficiency]
- **Database:** [SQL performance, missing indexes]
- **Network:** [Bandwidth limitations, latency]
- **System:** [CPU, memory, disk I/O]

#### Optimization Recommendations
- **Code Optimization:** [Algorithm optimization, caching strategies]
- **Architecture Optimization:** [Load balancing, distributed deployment]
- **Database Optimization:** [Index optimization, query optimization]
- **System Optimization:** [Hardware upgrades, parameter tuning]

### Risk Assessment
| Risk Item | Impact | Probability | Response Measures |
|-----------|--------|-------------|-------------------|
| [System overload] | High | Medium | [Resource protection mechanism] |
| [Data loss] | High | Low | [Data backup plan] |
