JDiskMark is a powerful and versatile disk benchmarking tool written in Java, designed to help you accurately measure the performance of your storage devices across different operating systems. Whether you're testing HDDs, SSDs, or network drives, JDiskMark provides reliable insights into your disk's read and write speeds. ubuntu/debian: https://sourceforge.net/projects/jdiskmark/files/jdiskmark_0.7.0_amd64.deb/download rhel / fedora: https://sourceforge.net/projects/jdiskmark/files/jdiskmark-0.7.0-1.x86_64.rpm/download macos: https://sourceforge.net/projects/jdiskmark/files/jdiskmark-0.7.0.pkg/download windows: https://sourceforge.net/projects/jdiskmark/files/jdiskmark-0.7.0.msi/download note: elevated privileges allow jdiskmark to automate clearing of disk cache. ZIP releases require java to be installed separately: * 0.6.3-current > jdk25 * 0.5.0-0.6.2 >jdk21 * 0.1-0.4 > Java 8

OpenGLChecker is a fast and smooth program that retrieves relevant information about your OpenGL implementation. It can also test your computer's performance with fully scripted benchmarks. This allows you to write your own benchmark scripts for testing your OpenGL performance.

Having been a Mac OSX user now for some years I appreciate the simplicity of CoconutBattery (http://www.coconut-flavour.com/), which shows you all relevant information of the battery of your laptop (iBook, PowerBook, MacBook, ...) and has one outstanding feature: you can save the current health state of the laptop's battery and thus monitor the long term development (degradation) of the battery. Since I have to work in Windows at work :-( I was looking for a similar tool in the MS world. You can find a number of battery monitoring programs for MS Windows, which give you a plethora of (useless) information - or do not work at all. Finally I decided to make one of my own (the world waited for that so badly!). And here it is. Since I did not want to restrict it to Windows only I made it a GTK application, which is cross platform portable. I created the low level data gathering functions for both Windows and Linux. You are very welcome to add additional ports (e.g. BSD or whatever).

Fast Elixir is a curated collection of performance-focused best practices, idioms, and code snippets for writing efficient Elixir programs. The project documents common patterns in Elixir and compares their relative performance using benchmarks to guide developers toward faster and more memory-friendly code. By showcasing side-by-side examples, it highlights not only which approaches are faster but also why certain functions or techniques should be preferred in different scenarios. The repository is designed as a practical reference for developers who want to optimize Elixir applications without diving into premature micro-optimizations. Its goal is not just speed but also clarity, ensuring that performance improvements do not come at the cost of readability and maintainability. With continuously updated examples, Fast Elixir helps both beginners and experienced Elixir programmers adopt better habits and avoid slow patterns.

DiskMarkStream is an automatic macro tool specially designed for CrystalDiskMark (CDM). It will run CDM with predefined settings and save screenshot and log. This consecutive unattended operation will help user to test various conditions and multiple drives at ease.

This benchmark suite is intend as a tool for the research community. It consists of a set of open source, real world applications with non-trivial memory loads.

Utility for testing CD/DVD quality and transfer rate written on C++ and Qt

QuickMAN is a Mandelbrot fractal generator with multicore support. ASM-optimized code can reach over 100 billion iterations per second. Features an easy-to-use GUI, realtime pan/zoom, multiple palettes, image logging, and saving in PNG format.

New owners (Oracle), new rules: Vdbench has been moved to Oracle Technology Network (OTN) http://www.oracle.com/technetwork/server-storage/vdbench-downloads-1901681.html

The Activity Indicator utility is a simple program that indicates the HDD activity in the system tray. It contains advanced logging capabilities and friendly interface. It can be used to log the drives and supports indication of many drives by running multiple instances. Now with better, brand new interface!

This Solaris system monitoring tool allows to perform standard SAR activity reporting and NMON activity reporting. The NMON output can be imported with Excel or RRD to output simple and efficient graphs.

File Read Test is a tool that reads disk files or directories and stops on the first read error. A second tool, Quick Disk Test, fills a disk with test data and verifies that it can be read back without errors.

7-max increases the performance of some applications up to 10-20%. Windows uses small (4 KB) RAM pages by default. 7-max allows to use large (2 MB) RAM pages.

HeavyLoad is a stress-testing tool by JAM Software that evaluates a computer’s performance by placing high loads on various system components, including CPU, GPU, RAM, and hard disk. It’s designed to test system stability under extreme conditions, useful for assessing reliability and identifying potential hardware bottlenecks or failures.

HardInfo displays information about your hardware and operating system.

powerMAX is a CPU and GPU burn-in tool designed to push your hardware to its absolute thermal and power limits. It helps users uncover stability issues, cooling weaknesses, and power delivery problems by applying maximum, sustained stress to both the processor and graphics card. The utility supports dedicated CPU tests—SSE or AVX—and a demanding GPU 3D rendering test, with the option to run both simultaneously for full-system power load evaluation. Because it does not generate scores or benchmarks, powerMAX is strictly a stress-testing tool rather than a performance comparison utility. The software requires no installation, leaves no system traces, and runs on any Windows system from Windows 7 onward. Users must operate powerMAX at their own risk, as the extreme loads can expose component flaws and potentially cause irreversible hardware damage.

Master/node to gather and graph "everything" on your systems using Tobi Oetiker's rrdtool. It can optionally warn your surveillance software. This software package was originally called LRRD. The project. Please see http://munin-monitoring.org/
