Different types of stress testing software exist, covering a range of operating systems and hardware components, including CPU cores, graphics cards, and RAM. Testers have the ability to simulate thousands, or even millions, of users to exercise the resources on their network beyond normal operating points. 

Determine how far you can push the limits of your machines and software with these top stress testing tools. 

Comparison Criteria

Here are helpful criteria you can use to evaluate different stress testing software: 

  1. User Interface (UI): Simple point-and-click GUI interfaces help you quickly run stress tests and download results. 
  2. Usability: Good software usability ensures your team can learn and perform the necessary steps to conduct stress testing. 
  3. Programming Language: Stress testing tools with lightweight code won’t add an extra burden to your system. 
  4. Portability: Portable stress testing software allows you to transfer the program to multiple computers and operating systems.  

Stress Testing System: Key Features

Look for these key features to get the most value from your stress testing tool:

  1. Robust User Simulation: Tools that can simulate a large number of users with varying attributes provide a realistic view of your computer’s stability during extreme conditions. 
  2. Real-Time Monitoring: Testers can quickly identify and debug issues with real-time monitoring.
  3. Add-ons: Many stress testing applications offer add-ons that testers can use to expand the software’s functionality. 
  4. Remote Testing: Remote testing enables you to exercise computers with limited network capabilities that can’t simulate large volumes of users.

LoadTracer

Lightweight stress, load, and performance testing software for web applications

LoadTracer is a free GUI-based tool for load, stress, and performance testing of web applications. The software was developed in C language, making it a lightweight tool that won’t put an extra burden on your operating system’s performance. Testers can generate thousands of virtual users to execute simulations and follow up with LoadTracer’s analyzer tool to assess their system’s stability and performance.

With LoadTracer’s parameterization functionality, testers can generate different attributes for each virtual user. It makes load tests more realistic since real-world users behave as individuals rather than clones of each other. Duplicating tests across different platforms is also easier. Instead of re-scripting a test for each new environment, testers can simply change one parameter value.

LoadTracer is proxy-based, enabling testers to utilize the tool on any browser.

LoadTracer is free to use.

5

Core Temp

Monitors temperature of processing cores in real-time

Core Temp is a compact Windows gadget that monitors processor temperature and load, frequency, and VID settings. The tool can provide temperature readings for the individual cores of every processor within a system during stress testing. As your system’s workload changes, Core Temp displays temperature fluctuations in real-time.

Temperature readings are collected directly from a digital thermal sensor located near the hottest part of each processing core in your system. Digital thermal sensors don’t rely on external circuits located on the motherboard to report temperature, resulting in highly accurate readings.

Core Temp supports Intel, AMD, and VIA processors and is also motherboard agnostic. Developers can also leverage plug-ins, like Core Temp MC, which can display the status of a processor directly from the Windows Media Center UI.

Core Temp is free for all users, with apps available for Android and Windows devices to monitor your system on the go.

6

HWiNFO64

Hardware analysis, monitoring, and reporting software for Windows and DOS

HWiNFO64 is a comprehensive solution for hardware analysis and monitoring. It allows users to scan PC components and receive in-depth information about the operating system, processor, RAM, and storage. HWiNFO64 supports various operating systems, including DOS, Windows 95, Windows 11, and WinPE.

Real-time monitoring allows users to quickly diagnose and take action on issues, like overheating or system overload, affecting their PC’s performance. HWiNFO64’s monitoring tool covers CPUs, GPUs, mainboards, drives, and peripherals. Users can create customizable reports and alerts for any monitored PC component.

Add-ons are available to expand HWiNFO64’s functionality, including plug-ins for Rainmeter, Samurize, and Elgato Stream Deck.
