The freeware stress test tool HeavyLoad was developed to bring your PC to its limits. It can be installed on any edition of Windows and client/server versions (32-bit and 64-bit) currently supported by Microsoft.
HeavyLoad puts your workstation or server PC under a heavy load and lets you test whether they will still run reliably.
Prime95 is a CPU stress test and benchmark tool popular among overclockers. It’s part of a distributed computing project for finding Mersenne prime numbers, but it includes torture test and benchmark modes. It’s an older app, but will work with pretty much any version of Windows—from XP all the way through 10. HTTP Stress & Performance Tests The applications that make up the current OpenSTA toolset were designed to be used by performance testing consultants or other technically proficient individuals. This means testing is performed using the record and replay metaphor common in most other similar commercially available toolsets. FurMark is a lightweight but very intensive graphics card / GPU stress test on Windows platform. It's a quick OpenGL benchmark as well (online scores). FurMark is simple to use and is free. Like Packet Sender, this tool could be more user friendly. And as with most open source and free network stress test software, it’s not suited to business needs. It’s available for Linux, Mac, and Windows and is simple to download and install. The source code is accessible from the download page. The “Paint-Stress” GPU test is enabled by default and the “HD-test” and a more aggressive CPU test which will push your processor towards 100% (the standard test used about 60% of a dual core CPU during testing) can be enabled by the buttons at the top of the window.
Be mobile: Install HeavyLoad as a portable version e.g. on a USB stick and use it wherever needed!
The main window offers a clean and modern user interface which allows to quickly start the application and to see the stress HeavyLoad puts on your PC.
In the „Options“ dialog you can configure the tool according to your requirements or set advanced settings such as time limit or used CPU cores.
The Windows Task Manager can be opened from within HeavyLoad via the Extras menu to quickly assess your system's performance.

5 Stars Rating:
Heavyload is a System Utilities Benchmarking software developed by JAM Software GmbH. To stress your PC or server, HeavyLoad writes a large test-file to the temp folder, it allocates physical and virtual memory, performs complex calculations and it draws patterns in its window.
ServerSentinel
No more server stress-out
Use sensors to automatically and continuously monitor CPU and memory usage. No longer worry about processor load limits!
| What is OpenSTA? Open, Systems Testing Architecture |
OpenSTA is a distributed software testing architecture designed around CORBA, it was originally developed to be commercial software by CYRANO. The current toolset has the capability of performing scripted HTTP and HTTPS heavy load tests with performance measurements from Win32 platforms. However, the architectural design means it could be capable of much more.
| Web Load Testing HTTP Stress & Performance Tests |
The applications that make up the current OpenSTA toolset were designed to be used by performance testing consultants or other technically proficient individuals. This means testing is performed using the record and replay metaphor common in most other similar commercially available toolsets. Recordings are made in the tester's own browser producing simple scripts that can be edited and controlled with a special high level scripting language. These scripted sessions can then be played back to simulate many users by a high performance load generation engine. Using this methodology a user can generate realistic heavy loads simulating the activity of hundreds to thousands of virtual users.

| Data Collection Timers, Windows Performance & SNMP Statistics |
Results and statistics are collected during test runs by a variety of automatic and user controlled mechanisms. These can include scripted timers, SNMP data, Windows Performance Monitor stats and HTTP results & timings. Much of the data logged can be monitored live during the test runs; once test runs are complete, logs can be viewed, graphed, filtered and exported for use by more sophisticated report generation software.

The OpenSTA toolset is Open Source software licensed under the GNU GPL (General Public License), this means it is free and will always remain free. If you wish to build your own customized version of OpenSTA or take part in its development then the complete toolset source code, buildable in Microsoft Visual Studio 6, and all related information is available from OpenSTA.SourceForge.net, the developer home site.
| Community Supported Development Driven by the Users |
Much more information can be found out about OpenSTA by checking the online documentation or simply downloading and installing the toolset. The FAQ contains lots of other useful background information and helpful tips, this should be the first place you look if you need help with anything not covered in the documentation. There is no need to stop at reading the FAQ either, it is hosted on the OpenSTA Community Portal and, in common with every other resource on this site, it is user editable. This site is a great place for every OpenSTA user to share their experiences with the product and help others learn and use OpenSTA: Remember, the toolset is completely free and any time the developers spend helping users is time they are not enhancing, or fixing problems with, the toolset. By helping other users you are in fact helping OpenSTA and its community become stronger. The premier place for free OpenSTA support and discussions is the OpenSTA Users Mailing List, here the developers and many long time users of this toolset give as much help as their freetime will allow.
