What is Jmeter?
Apache Jmeter is easily one of the most used performance testing tools for developers which can help you perform web service testing. It is available in open-source format, which makes it highly accessible to software businesses of all sizes. Furthermore, the performance testing tool supports a 100% Java scripted desktop application and also tests the functional performance of web applications.
What makes this Jmeter unique is that it’s extremely versatile despite being open-source. The tool is compatible with a number of protocols web and networking protocols such as HTTP, HTTPS, FTP, LDAP, SOAP, and TCP. Since the application has a Java-oriented system, it also offers compliance with JDBC and Message-oriented middleware (MOM) through JMS.
At the same time, Jmeter is compatible with email protocols such as IMAP(Server), POP3(Server), and SMTP(Server). These protocols help you reinforce security standards in used email transfer within your application. The option of using shell scripts and native commands during testing procedures makes it easier to implement during testing procedures.
Moreover, Jmeter offers software testers the opportunity to test their applications for both dynamic and static resources, such as queries, servers, logs, scripts, and files. Similarly, testers can also inspect applications heavy load applications and evaluate their robustness and performance against varying load types.
Lastly, Jmeter is also highly extensible and therefore, compatible with a number of third-party integrations and plug-ins. These plug-ins and third-party tools provide you with additional software testing features. Ultimately, the robust nature of Jmeter makes performance testing extremely easy across several servers, testing platforms, and browsers.

Web applications are designed and developed on a mass scale all-around the world. With so many options available, users only go for software applications that give them the best results. Therefore, your web application has to be optimized for maximum performance in order to stay ahead of the competition.
Apache Jmeter is the perfect performance testing tool for web application testing. It offers users various capabilities for performance testing and integration. Therefore, you cannot only evaluate the functional capabilities of web services and apps, but also measure load strength and compatibility across several platforms.
Furthermore, software testers have the option to transfer testing tools for various servers and browsers. At the same time, Apache Jmeter offers robust features for running tailored tests on protocols such as HTTPS and HTTP for web, SOAP, POP3, JMS, and SMTP. As a result, you can ensure that your web applications are high-performing and error- free.
At the same time, since the tool is available in an open-source framework, users of the tool can easily customize and develop features within the existing framework. This feature also gives software teams the freedom to create their structural test designs and infrastructure for web applications. The open-source framework also encourages developers to create an inclusive community of users.
Apache Jmeter currently has the following integrations:
- Visual Studio

What is LoadRunner?
HP Loadrunner (now Micro-Focus Loadrunner) is a highly sophisticated software performance testing tool that detects and prevents performance issues in web applications. It specializes in detecting bottlenecks before the application enters the implementation or the deployment phase. Similarly, the tool is extremely helpful in detecting performance gaps in before a new system is implemented or upgraded.
However, Loadrunner is not limited to testing web applications or services. The application is also optimized for testing ERP software, legacy system application, as well as Web 2.0 technologies.
LoadRunner Cloud on AWS is a great scalable cloud-based load testing service for the fast-moving agile teams.
Loadrunner enables software testers to have complete visibility over their system’s end-to-end performance. As a result, these users are able to evaluate each component individually before it goes live.
At the same time, Loadrunner also gives its users highly advanced forecasting features for forecasting expenses for up-scaling application capacity. By precisely forecasting expenses related to both software and hardware, it is easier to enhance the capacity and scalability of your application.
Loadrunner is not open source, and is owned the technology giant Hewlett Packard. Therefore, the code of the application is not available to users. However, since the application already offers many advanced and high-level testing features, it isn’t necessary to customize existing features.

What isPFLB Platform?
PFLB Platform is the new generation product which allows running tests in the cloud to all audiences interested in load testing. You can be a marketer, product or project manager, developer or unsurprisingly performance engineer and you would be able to use PFLB Platform to achieve your goals.
For marketers PFLB Platform provides an easy-to-use instrument which integrates with Google Analytics and Yandex.Metrika to retrieve statistical information and run performance tests without any coding or other engineering.
Developers and performance engineers will find PFLB Platform handy for conducting performance tests in the cloud. They can have a full suite of testing tools, such as HAR/Insomnia import, request definition, parameterization and correlation running in the cloud as SaaS service without need to worry about infrastructure deployment etc.
Product and project managers will be happy to analyse the results of the recurring tests online using grafana dashboards.
Overall, PFLB Platform represents a new generation of the performance testing products which allows to easily create, plan, run and execute tests in the cloud, using a simple and straightforward WEB interface.
PFLB PlatformFeatures in Performance and Load Testing
Test profile creation
One of the most complicated steps in performance testing is to create a realistic load profile. PFLB Platform helps to solve this problem by importing statistical information from Google Analytics, Yandex.Metrika and other statisticals systems. That allows to reduce tedious hours of work in Excel to a few clicks and generate a very realistic profile.
Nevertheless, once the profile is created users, especially technical ones, might want to adjust requests which are being sent to the system. PFLB Platform provides easy-to-use test editor which allow to create and edit all kinds of HTTP(-S) requests, including body, headers and parameters.
Those requests could be parameterized with variables defined as multi-value CSV parameters or single-value global constants.
Sometimes parameter values described above need to be extracted from the responses. PFLB Platform allows to do so with regex, jasonPath and boundary conditions
Recording and imports
To simplify test creation you can record and import multiple requests using built in Chrome functionality (exporting requests to HAR) or import Insomnia package.
Pros and Cons of PFLB PlatformApplication
PFLB Platform is the next generation of performance testing products, trumping JMeter and Loadrunner in all aspects.
PFLB Platform advantages:
- Web interface
- Ease of use
- Integration with Google Analytics and Yandex Metrika
- Import of HAR and Insomnia
- Cloud deployment
PFLB Platform disadvantages:
- Currently PFLB Platform supports performance testing of HTTP(-s) applications such as websites, API and apps
- PFLB Platform doesn’t have a thick desktop client but this is resolved with export to JMeter standard JMX
When Do You Need to UsePFLB Platform?
Are you testing website, API or app ? Use PFLB Platform and accelerate your testing cycles by a magnitude. Don’t have experience in performance testing – you don’t need any with PFLB Platform.
If you are testing some proprietary not web-based systems else stick with loadrunner or jmeter.
PFLB Platform Integrations
- AWS Cloud Development Kit
- GitLab ci/cd
- Google Analytics
- Yandex Metrika
LoadRunner, Apache Jmeter and PFLB Platform are excellent performance testing tools depending on your testing needs.
If you are looking for tool that gives you in-depth bottleneck detection and root-cause analysis as well as other advanced testing features, then you should consider Loadrunner.
