    I was highly satisfied working with PFLB. They're a fantastic one-stop shop for software performance, with everything you need—their platform and skilled engineers. I've used them three times to load test the College Board software before big updates, and it all went smoothly. Plus, I love that they store all the testing data, so we can track performance capacity over time.

Frequently Asked
Questions

What Types of Website Load Testing Does PFLB Support?

PFLB supports a variety of website load testing types to help you comprehensively assess your site’s performance under different conditions:

  1. Stable Load Testing: This test maintains a consistent number of virtual users (VUs) throughout the testing period, allowing you to evaluate how your website performs under a steady load.
  2. Scalability (Ramp-Up) Load Testing: In this test, the number of VUs gradually increases over time, helping you understand how your website scales as traffic grows and identifying at what point performance begins to degrade.
  3. Spike Load Testing: This test introduces sudden spikes in traffic to see how your website handles abrupt increases in load, which is crucial for understanding performance during unexpected traffic surges.
  4. Stress Testing: PFLB can push your website to its limits by increasing the load beyond normal operational capacity. This helps you identify the maximum load your site can handle before it starts to fail or degrade significantly.
  5. Custom Load Testing: PFLB allows you to create highly customized load testing scenarios tailored to your specific needs, combining different types of load patterns and virtual user behaviors.

These diverse testing options provide you with a comprehensive understanding of your website’s performance, ensuring it’s well-prepared for real-world traffic conditions.

Can I Run My Existing JMeter Load Tests on PFLB’s Cloud?

Yes, you can easily run your existing JMeter load tests on PFLB’s cloud. Simply upload your JMX files to PFLB, configure the test settings as needed, and execute the test across our distributed cloud infrastructure. This enables you to run large-scale tests without the need for extensive local resources, providing you with detailed insights into your website’s performance under various load conditions.

How Do I Load Test My Website?

To load test your website with PFLB, follow these steps:

  1. Sign Up or Log In: Begin by signing up for an account or logging into your existing PFLB account.
  2. Choose Your Test Method: After logging in, you can either create a load test from scratch or select the “Run your own JMeter” option. If you choose to create a test from scratch, you’ll define your load testing scenarios by adding pages and specifying GET or POST requests one by one using the no-code script builder.
  3. Set User Load and Test Type: Determine the number of virtual users (VUs) you want to simulate during the test. Additionally, choose the type of load test you want to run—either a “stable” test to maintain a consistent number of VUs or a “scalability” test where the number of VUs gradually increases over time.
  4. Run the Test: Execute your test by starting it within the platform. PFLB will simulate the defined load on your website and monitor its performance under the specified conditions.
  5. Analyze the Results: Once the test is completed, review the performance metrics provided in the Grafana dashboards. These detailed insights will help you identify any performance bottlenecks and optimize your website for better traffic handling.

This process enables you to thoroughly evaluate your website’s readiness to handle real-world traffic loads.

Can I Simulate Traffic from Different Geo Locations?

Yes, with PFLB, you can simulate traffic from different geographical locations. This allows you to test your API’s performance and latency across various regions, ensuring it can handle global traffic efficiently. Simply configure the load generator locations within the PFLB platform to distribute the load as needed.
