Load Tests: Jmeter vs PFLB

Published on July 6, 2024

When it comes to load testing tools, there is a recent tool called PFLB which I received a comparison with the most popular one: JMeter. Each has its own strengths and weaknesses, making them suitable for different scenarios. Let’s delve into a comparison between the two.

PFLB JMeter




Support
– HTPS(S)
– SOAP
– REST
– FTP
– LDAP
– WebSockets
– SMTP/POP3/IMAP
– Citrix ICA
– HTTP
– FTP
– JDBC
– SOAP
– LDAP
– TCP
– JMS
– SMTP
– POP3
– IMAP




Speed to Write Test
Fast Slow




Support of “Test as Code”
– Limited Support
– Scripting
– Control Version
– CI/CD Integration
– Reusability
– GUI oriented
– Possibility to create scripts, but too complex and lack of documentation
– Weak (Java)
– Hard to maintain




Ramp-up Flexibility
User-Friendly through GUI Plugins available to be able to configure flexible load




Test Result Analyzing
Yes Yes




Resource Consumption
Optimizing resource usage involves properly configuring test scenarios and monitoring performance to adjust as needed. Heavy to run tests with multiple users on a single machine, more memory consumption




Easy to use with Version Control Systems
Yes No




Recording Functionality
Yes Yes




Distributed Execution
Yes Yes




    Load Test Monitoring 
It reduces memory consumption through asynchronous logging, cloud-based infrastructure, and integration with specialized monitoring tools. Ability to monitor a basic load

PFLB is most used when you need: 

  • Scalability: PFLB tool offers cloud-based load testing, allowing users to scale tests to simulate millions of users without worrying about local resource limitations.
  • Integration: It integrates seamlessly with other monitoring and APM tools (e.g., New Relic, Dynatrace, Datadog), providing comprehensive performance insights and real-time analytics.
  • Ease of Use: PFLB tools are easy to use, with intuitive interfaces and detailed reports, making it easy for teams to set up, run, and analyze load tests.
  • Enterprise-Level Support: PFLB provides robust support and customization options for enterprise clients, ensuring that specific performance testing needs and requirements are met effectively.

JMeter solves some specific problems:

  • Identifying Performance Bottlenecks: JMeter helps detect slow or underperforming parts of an application by simulating various load conditions and monitoring response times.
  • Scalability Testing: It evaluates how an application scales with increased load, ensuring that the system can handle expected traffic and identifying any points of failure.
  • Concurrent User Simulation: JMeter can simulate multiple users accessing the application simultaneously, allowing testers to observe how the application behaves under concurrent usage.
  • Regression Testing: It can automate performance tests as part of a continuous integration process, ensuring that new code changes do not degrade application performance.
