User Simulation

Please enter the Number Of Users Webserver Stress Tool should simulate. This is the number of users that simultaneously use your website.

The Number of Users can be a value between 1 and 10.000. But remember that the maximum number of simultaneous users that can be successfully simulated depends on the computing power of the client machine running Webserver Stress Tool and various parameters that you set later.

Webserver Stress Tool always shows the CPU load in the statusbar at the bottom and also generates a “client health” chart during the test. If you client machine runs at 100% CPU load you have hit your machine’s limit.

Next, you have to enter the Click Delay time for the simulated users. This setting is as important as the Number of Users. The lower the delay time between clicks, the greater the level of stress on your webserver.

Look at the “estimated load” calculation below the click delay setting to see what load your settings will create.

Important: These two values are the most critical values you will enter!

To create the highest possible load set the delay time between clicks to 0 (zero). This way Webserver Stress Tool will send the next user request immediately after the previous request is finished. Please note: When using the value of zero a setting of 40-80 users should  be enough for most tests (higher values can decrease the load because of multithreading overhead).

By enabling Random Click Delay you can tell Webserver Stress Tool to randomly use a delay time between two clicks that is between 0 seconds and the number of seconds you entered in Click Delay. This will make the test pattern even more dynamic but a little less reproducible.
