Load testing services – are specialized software testing services that aim to define and gather the performance indicators and response time performance of a system or a gadget. All these is done to map the requirements imposed on the given system.
Reasons to Perform Load Testing Service:
- Validate & optimize the configuration of hardware, virtual machines, server software.
- Assess the maximum performance, which, a project with typical load scenarios on available resources can withstand.
- The impact of project modules on the performance, scripts for handling peak loads.
- The assessment of stability at maximum loads, when conducting a 24-hour testing & considering external factors, like imports, backup, etc.
- Identifying of confined configuration, defining the methods of further scalability and optimization.
In general, there is a great variety of an open source and commercial tools used by the majority of load testing companies. Let’s focus on the most used ones & share their main options.
#1. Apache HTTP Server Benchmarking Tool
This tool is free and used very often since it included as a compound of Apache. It does not require any additional configurations and is user-friendly. Apache Bench (ab) tool aims to help you in defining the maximum number of simultaneous requests, which can be processed by your web server installation.
Apache Drawbacks Are:
- It is too easy tool.
- Test only the web-server performance: polls only one URL, does not support the load scripts, it’s hard to imitate the user load and assess the project workability and from infrastructure point of view, and from development one.
#2. Apache JMeter
Apache JMeter is free for use, handy, and powerful tool. Among its main properties, we may single out the following:
- Written on Java.
- HTTP, HTTPS, SOAP, Database via JDBC, LDAP, SMTP(S), POP3(S), IMAP(S).
- Consoles & GUI.
- Distributed testing.
- Test plan – XML-file.
- The ability to elaborate log of a web-server as a test plan.
- Visualization of GUI results.
Apache JMeter is cross-platform, since has been written on Java. This tool is flexible and is controlled via console & GUI. It also uses many protocols not only of a web-server, but also of the databases. Testers may use the logs of Apache & Nginx web-servers as a script with a further possibility to vary the load on these profiles.
Apache JMeter is quite data-hungry tool. On the long-term and complicated tests may fall for a variety of reasons. The stable workflow of Apache JMeter depends on the environment & service configuration.
