How to Validate Performance Under Different Loads in a Single Execution with AngusTester

Pain Points of Traditional Tools

Testing performance for 5000 users requires 50 configuration changes, 50 data recordings, and a cumulative 50 minutes of waiting time.

  name: Full Gradient Load Analysis Example
  description: Automatically validate system performance under different loads
type: TEST_PERFORMANCE
plugin: Http
configuration:
  duration: 50min              # Total test duration
  thread:
    threads: 5000               # Target maximum concurrency
    rampUpInterval: 1min        # Load gradient interval
    rampUpThreads: 100          # New concurrent users per gradient
task:
  pipelines:
    - target: HTTP

• Core Parameter Explanation

Parameter	Purpose	Configuration Tips
threads	Maximum concurrency	Set to 120% of expected peak
rampUpInterval	Load increase interval	Set based on business fluctuation characteristics
rampUpThreads	New concurrent users per increase	Recommended 5-10% of system capacity
delay=10	Interface simulation delay	Set to typical business response time

• Working Principle Diagram

Technical Advantage

Automatic Load Increase Mechanism: The system automatically adds 100 concurrent users per minute, achieving full gradient coverage from 0→5000 concurrency within 50 minutes.

Step 2: Configure Execution Task

1. Navigate to Execution → Add Execution.
2. Select the created intelligent script, confirm parameters, and save.

Step 3: Multi-dimensional Performance Analysis

Access the "Overlay Analysis" panel in execution details to:

• Correlate key metrics observation
  1. Concurrency Change Curve: Real-time thread growth tracking
  2. TPS Fluctuation Trend: System throughput change monitoring
  3. P90 Response Time: High-assurance performance level monitoring
• Identify performance inflection points
  • Discover performance bottlenecks
  • Locate resource saturation thresholds
  • Identify error rate mutation intervals
