Appvance IQ Load Generator Table

Use load-generator sizing tables as planning guidance, not as a substitute for calibration. ActualEstimated capacity dependsper onserver scenarioor complexity,VM browser(varies usage,greatly protocolwith mix,application data,complexity)

What

Refer affectsto loadthe generationtable

  • Browser-basedbelow virtualto usersdetermine versus protocol/API virtual users.
  • CPU, memory, disk, network, and operating system configuration.
  • Think time, pacing, response time, retries, and error rate.
  • Test Node count, geography, and application-under-test behavior.
  • Logging, screenshots, video, and evidence retention.

Validation workflow

  1. Run a single-user smoke test before load calibration.
  2. Increase concurrency gradually and monitor both AIQ and application resources.
  3. Identify whether bottlenecks are in load generation or the application.
  4. Document achieved capacity and assumptionsconfiguration forneeds: future

    Using the latest Chrome browser, poor linear scalability is experienced after 30 browsers regardless of the size of the test node.

    Example System Requirement Calculation

    If a test specification requires UX tests to run 1000 virtual users, and each test node has an 8 Core CPU with 12 GB RAM, then 20 test nodes are required.

    Calculated as:

    • Test Nodes Required = Total Virtual Users / Virtual Users per Test Node
    • (from the above example) 20 Test Nodes = 1000 Virtual Users / 50 Virtual Users per Test Node
