Analysis of load test results

Hello Sumedha,

1. If I calculate the Total time from the column Time(s) of connections ,it comes out to be 352.344.Is it not the same time as the total time displayed(323.71) in the Users part of the load test result.Also how do I evaluate my results .

To learn what is included in every time value, please see the HTTP Load Testing - Timing Task Execution help topic.

2. How is the performance(kb/s) calculated for each user.Which bytes(bytes received or bytes sent ) and time value and from which column of the load test results are being used to evaluate the perfromance in kb/s .

Let me quote the Load Testing Log Page help topic:



Values in this column are calculated by the following formula:

Performance = (Total Bytes Sent + Total Bytes Received) / Time

These values indicate the server performance when it was working with the connection.

3. Also the start delay column of the load result in connections part shows some delay for each of the connections. What does it depict? I did not mention any start delay while my load test run.

The "Load Testing Log Page" help topic describes this value:

The number of seconds passed from the start of the load test till the moment when the connection was established.

4. How are minimum and maximum response time calcualted for all the connections and which values from the log to be used for calculation ?

This can be done for a specific user in the following way:

- in the Load Testing Log, right-click within the Connections list;

- select "Show Summary" from the context menu - you will see the Summary panel at the bottom of the connections list;

- right-click within the Summary panel under the "Min response time" or "Max response time" column and select the type of the summary value you want to see.

By using this approach, you can see the minimum and maximum response time across connections.

How to measure the average response time for the total task execution.

TestComplete does not calculate this information automatically. The only way to get it is to access the Load Testing results from script and iterate through all requests' data to get the average response time. To learn how to do this, please see the Scripting Access to the Test Log Contents help topic.
