How to Use Application Load Testing

A brief description of how to use the Application Load Testing service

Use Webscale’s Application Load Testing service to perform a load test on your application with just a single click. You can then use the results of this test to find possible performance bottlenecks or code base errors with your application. It’s also a useful way to test your application after making changes to it, or to share the results with a developer or auditor.

Getting started

Once Webscale has added the Application Load Testing service to your account, meet with the test designer to discuss the specific needs of your application and how you’d like it to be tested. Once complete, the test designer will upload the test’s configuration file and you can run tests as you see fit.

Run a test

On the Application Testing page, select the parameters for this test. By default there are two (2) you can choose from, but depending upon the design of the test you may be able to choose more:

  • Virtual Users: The number of virtual users used by the test to simulate site visitors.
  • Duration: The length of the test, in seconds.
  • Target: The cluster or application to run the test against.

After making your choices here, click the Run Test Now button to run the test.

Interpreting results

When the test is complete the control panel will display the results. The test captures the following:

  • Request count
  • Average throughput
  • Average TTFB (time-to-first-byte)
  • Response count

This data is captured at each step of the test: ramp-up, each virtual user session used, and for the entire test duration. However, the ramp-up phase does not collect response codes. Note that a virtual user session fails if at least 30% of the response codes are in the 400/500 range.

Use these results to make changes to your application if needed, or share the results with your developer or auditors.
