Load Test Results Summary Overview

  • Article

 

After you run a load test, you can view the load test summary to understand the results quickly. The load test summary provides the key results in a compact and easy to read format. You can also print the load test summary. This makes it convenient to use when you communicate results to stakeholders. The load test summary is also the default view when you open a load test result from a previously run load test. For more information, see How to: Access Load Test Results for Analysis.

The Load Test Summary

The load test summary is divided into sections. The initial sections appear at the top of the summary, and are always visible. When you view the load test summary, the following items are first:

  • Test Run Information

  • Overall Results

  • Key Statistic: Top 5 Slowest Pages

  • Key Statistic: Top 5 Slowest Tests

  • Key Statistic: Top 5 Slowest SQL Operations

    Note

    The SQL Operations section is displayed only if SQL tracing is enabled in the load test.

The closing sections appear at the end of the summary, and can be collapsed to save space. The following items appear at the end of the load test summary:

  • Test Results

  • Page Results

  • Transaction Results

  • System Under Test Resources

  • Controller and Agent Resources

  • Errors

Test Run Information

The test run information section contains general information about the run including the name of the test, the start and end times, and the controller that ran the test. This section also contains the optional description of the run that you add when you run the load test.

Overall Results

The overall results section contains summary results of the test including the number of requests per second, the total number of failed requests, the average response time, and the average page time.

Key Statistic: Top 5 Slowest Pages

The slowest pages section contains the top 5 slowest pages in the load test. The URL and the average page load time are displayed for each page. The pages are listed in descending order. You can choose the URL of a page to open the Pages table and inspect more details for that page. For more information, see How to: View Web Page Response.

The percentile value for 95% Page Time (sec) report that 95% of the pages completed in less than this time in seconds.

Key Statistic: Top 5 Slowest Tests

The slowest tests section contains the top 5 slowest tests in the load test. The name of the test and the average test time are displayed for each test. The tests are listed in descending order. You can choose the name of a test to open the Tests table and inspect more details for that test. For more information, see Analyzing Load Test Results and Errors in the Tables View.

The percentile value for 95% Test Time (sec) report that 95% of the tests completed in less than this time in seconds.

Key Statistic: Top 5 Slowest SQL Operations

If SQL tracing is enabled in the load test, the slowest queries section contains the top 5 slowest queries in the load test. The name of the operation and the duration are displayed for each test. The duration is displayed in microseconds (SQL Server 2005) or milliseconds (SQL Server 2000 and earlier). The tests are listed in descending order by duration. You can choose the name of an operation to open the SQL Trace table and inspect more details for that operation. For more information, see The SQL Trace Data Table.

Test Results

The test results section contains a list of all the tests and scenarios in the load test. The name of the test, the scenario, the number of times it ran, the number of times it failed, and the average test time are displayed.
