FAQs

01How to Stress Test my REST API?

To load test REST API using PFLB, define your API requests manually with our no-code script builder or import collections from Postman or Insomnia. Configure the load generator locations, manage RPS (requests per second), test duration, and ramp-up. Run the test and analyze the results with PFLB’s custom Grafana dashboards for detailed insights.

02How to Choose API Methods for API Load Testing?

Select API methods that are critical to your application’s performance and user experience. Focus on endpoints with high traffic, complex operations, or those that handle large data volumes. Using PFLB API stress test tool, you can easily define and test these methods to identify potential performance bottlenecks and ensure your API can handle real-world load conditions.

03Can I Simulate Traffic from Different Geo Locations?

Yes, with PFLB, you can simulate traffic from different geographical locations. This allows you to run your performance testing for API across various regions, ensuring it can handle global traffic efficiently. Simply configure the load generator locations within the PFLB API load tester to distribute the load as needed. You also have the option to use the JMeter load testing tool for more customized test scenarios.

04What Types of API Does PFLB Support?

PFLB supports a wide range of API types, including RESTful APIs, SOAP, and gRPC. This versatility allows you to load test API of various architectures and ensure their performance under different load conditions.

05How to Load Test Postman Collections?

To load test your Postman collection follow these steps:

  1. Export the Collection: Open Postman, select the collection you want to load test, and export it as a JSON file.
  2. Import into PFLB: Go to the script builder interface and import the exported Postman JSON file. PFLB API benchmark tool will automatically create the necessary requests and scenarios.
  3. Configure Load Test Parameters: Set up the load test parameters within PFLB load testing tool for API. Specify the number of virtual users, test duration, and any other custom settings required for your API performance testing scenario.
  4. Run the Load Test: Start the load test and monitor its progress in real-time using PFLB’s dashboard.
  5. Analyze Results: After the test is complete, analyze the results using PFLB’s custom Grafana reports. Examine key performance metrics such as response times, error rates, and throughput to check scalability, and identify any performance issues.
