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**

Execution Instructions

1. Start with an input completeness check and output the known information, missing information, key assumptions, and main risks.
2. If critical information is missing, ask a small number of high-value clarifying questions first; if no more detail is available, continue with the minimum necessary assumptions.
3. Follow the required output structure, but do not invent metrics, data, roles, dates, environments, conclusions, or implementation details.
4. Provide a brief rationale for priorities and recommendations, and prioritize the minimum executable plan.
5. Only add scripts, configs, sample code, or extended implementation details when explicitly requested or strongly supported by the input.

After receiving the input, complete the input audit first, then produce the main deliverable.
