Load Tester™
Affordable enterprise-quality load testing tool
Unique Feature
How Many Users Analysis
Web Performance User Capacity Analysis clearly measures your site's capacity based on either simple performance goals or complicated Service Level Agreements (SLA). You can use our default performance goals, or get as detailed or as technical as you like.
Virtual Browser Load Testing Tool
HTTP-based record and configure load testing makes designing accurate load tests as easy as clicking links on your website. Generate up to 1,000,000 concurrent users in your lab or from the cloud.
Control Think Time
Add think time to simulate your users’ interaction on pages.
Automated Virtual User Configuration
If you'd prefer to use virtual users instead of real browsers, Load Tester automatically sets and tracks the dozens of parameters involved in every page request. Control the fields (cookies, query variables, ETags, etc.) that would trip up a manually-written script.
Custom Field Parsing
Load Tester can handle complicated form fields (e.g., a value that combines static and dynamic elements) with its custom value parser.
File Uploads
Include file uploads as part of your tests. Uploads can be automatically varied (different types and sizes) to match real-world conditions.
SSL
SSL support is a requirement for many websites, and Load Tester has it covered.
API Load Testing
Test your back-end APIs directly.
No Coding
Configuring user input such as user names and passwords, search terms, and other user-entered fields is as easy as clicking on the field; no coding required.
Logins/Authentication Support
Straightforward support for several authentication protocols.
Parameterization
Have total, visual control of all page request fields. Mass edit, set data sources and more.
Multiple Browser Support
The popular browsers are configured automatically. And if you need it, any browser on any device can also be recorded if configured for a proxy.
Automatic Error Detection
Make sure the pages you're testing are the pages you expect. Load Tester detects application and logic errors and alerts you of unexpected responses.
Mobile (Android/iOS)
Mobile devices are on the rise. Load Tester accurately simulates the unique aspects of mobile browsers – like socket connections and caching behavior.
Run Your Tests. Repeat.
Years of experience has been incorporated into Load Tester test running. Tests automatically and deftly handle many server and client variables – firewalls, load balancing and cookies just work. And you can run realistic load tests as soon as you finish installing.
Cloud Load Generation
At the push of a button you can generate load from outside your network to test the entire application stack, including the firewall.
Auto-Scaling Server Support
If your server setup is dynamic (e.g., spinning up new instances under heavy load), Load Tester will recognize the change and test appropriately.
Bandwidth Test
Accurate measurement of Web Bandwidth eliminates confusion about slowdowns. Distinguish between application performance problems and issues with limited bandwidth.
Cookies
For the vast majority of applications, Load Tester's cookie support is fully automated. Years of usage with real-world websites has ensured compatibility with the vast majority of applications.
Internal Load Generation
The internal load generator is fine-tuned to be accurate and automatic. You can run realistic server tests after installing on just one machine.
Scheduled Tests
Load tests don't need a baby sitter. Easily schedule load tests to run in off-hours.
Server Monitoring
Learn exactly why performance is degrading under load with the Server Monitoring add-on.
Firewall Support
Many firewall configurations are supported.
Comprehensive Reports
Turn data into understanding with Load Tester reports. The Executive Summary and Performance Goals sections explicitly summarize the pages that need troubleshooting, in an easy-to-read checklist. And every bit of data is charted for additional analysis.
Advanced Metrics
Any load testing tool will report the page load time. Load Tester goes far beyond this simple view of web performance, recording 15 metrics for every page and 20 for every transaction in the test.
How Many Users Analysis
User capacity analysis clearly measures your site's capacity based on either simple goals or complicated Service Level Agreements (SLA). The user capacity overview helps you easily see how many users your site can handle.
Performance Goals (SLA)
Interpreting Load Tester reports is easy. You can find out, in an easy-to-read checklist, exactly which pages failed your specified performance goals at each level of users.
Learn MoreVisual Page Comparison
Load Tester makes it easy to see what the user saw. Compare what the Virtual User sees with a recorded view of the page.
Learn MoreHandle Modern Web Technology
The modern web is more complicated than single page loads. If your web product uses AJAX requests or responds with JSON data, you can trust Load Tester to react correctly and continue giving you the most accurate performance measurements.
AJAX
There's more to websites than the first page load. Load Tester understands AJAX requests and won't leave them out when calculating site performance.
JSON
When Load Tester recognizes JSON content in an HTTP request, it automatically adds it to the Fields View where it can configured and replayed.
Web Services
Load Tester works with products besides web pages. If you have a web service, you can configure a load test of the request/response cycle.
XML
Load Tester recognizes XML data and can expose its entire hierarchy in the Fields View.
API Load Testing
Test your back-end APIs directly.
