Get Insight Into Your Web Application Responsiveness

Interactive performance reports of your website allow to quickly isolate problem areas by navigating from the load test summary report to a hyperlinked transaction or web page sub report, and even further to individual requests and HTTP headers and bodies. Every performance report features a set of graph, grid, and document views.

Interactive Subreport for Every Web Page and Transaction

In graph view, click or mouse over virtually any element to display more details and drill down or expose additional performance analytics functionality.

Why load testing web site performance.
Open one or several test
reports in separate tabs
From the toolbar, select
between multiple graph, grid,
and document views
Select an area to zoom-in
Right-click on a graph
to customize its view
Click on a graph to
highlight its curve grid
Click on a page link
to open a page sub-report
in a new tab
From a test report open subreports for any page or transaction in separate tabs
From the drop-down,
select a graph
Right-click on any curve
to expose curve-specific
Mouse over a threshold
violation or a data point
to display its value
Click to sort and
select the slowest page

Dual Waterfall: Performance Vulnerabilities Exposed

Now for the first time in load testing, you can compare side-by-side waterfalls of a page, transaction or the entire test case, executed by two different virtual users during any selected test iterations, and immediately visualize which requests' responsiveness is impacted by the stress levels most. This new instrumentation allows to analyze web application responsiveness on a very granular level. Pick and choose any VUs and Iterations from the test activity diagram to analyze unusual patterns.

Why load testing web site performance.
Click on the timeline to see which VUs were active at this moment
Click on a VU to visualize its activity
Mouse over an iteration to display its performance
Double-click any HTTP session bar to open a session inspector with its content in a new tab
At a glance, detect vulnerabilities
to increased load resources
impacting page responsiveness
Pick and choose any two VUs or iterations and compare their performance on the dual waterfall chart
Hover over a request to display a tool-tip with its timing information.

Get Concrete Answers to Hard Performance Questions: How Many Users Can Your Site Handle?

Get concrete answers to the critical performance questions in the interactive test reports. In this test, when the number of virtual users reaches 44, the slowest web page will consistently miss its speed target.

Why load testing web site performance.
1. Run a step-load test and
open the slowest page subreport
2. Note the actual response
time curve and its goal line
5. Mouse over a point where the red line intercepts the users' line. The tooltip shows the answer - 44 users
3. Click the area where average response time consistently exceeds the goal
4. The red vertical line correlates response time to the number of users.
