I/O performance Analysis Tool
Linux performance monitoring on-screen or to CSV file
nmon is short for Nigel's Performance Monitor It either shows you the stats on-screen updating once a second or saves the data to a CSV file for later analysis and graphing. For details see the homepage ==> http://nmon.sourceforge.net Please use the latest version. The new version "njmon" outputs JSON format that a lot of tools use these days.

BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering & geometric analyses, network distributed framebuffer support, image & signal-processing tools.
lmbench is a suite of simple, portable, ANSI/C microbenchmarks for UNIX/POSIX. In general, it measures two key features: latency and bandwidth. lmbench is intended to give system developers insight into basic costs of key operations.
pdfcrack is a command line, password recovery tool for PDF-files.
System Stability Tester is a multi platform open source clone of SuperPI and comes with a GUI and a CLI. It can be used for CPU and RAM burning, stressing and benchmarking.
Portable, fully-threaded I/O benchmark program
NetIO-GUI measures network speed between two peers
NetIO-GUI is a Windows frontend for the multiplatform commandline utility 'netio'. It measures ICMP respond times and network transfer rates for different packet sizes and protocols. All results are stored in a SQLite database file and can easily be compared. NetIO-GUI is preferred to rate the quality of peer-to-peer connections like VPN. Download as portable 7-Zip or as setup file.
Yet Another Process Monitor (YAPM) is a powerful process viewer for Windows that monitors the services & processes, their modules, threads, handles, windows, TCP/UDP connections... etc. running on local system or on any of the computers on your network.
Windows tray HDD led like indicator with keyboard lights support.
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!
Utility application to obtain data about your OpenGL implementation.
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.
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.
Simple viewer for Fraps 'frametimes' benchmark results
Fraps has the ability to tell us the amount of time each frame took to display. With this program, it becomes easy to view this information as a chart, in overview or in fine detail. Hopefully this will help the Fraps user community to spot troublesome hardware or software setups.
Little Registry Cleaner is an open source program designed for Microsoft's Windows Registry. Its purpose is to remove obsolete or unwanted items that build up in the registry over time in order to improve the stability & performance of your computer
QuickMAN is a Mandelbrot fractal generator with multicore support. ASM-optimized code reaches billions of iterations per second on fast CPUs. Features an easy-to-use GUI, realtime pan/zoom, multiple palettes, image logging, and saving in PNG format.
Java Disk Benchmark Utility
Simple Java utility to help bench mark disk IO. Benchmark is done by creating and reading data files to a user directory that can be configured. If you find this tool useful a review and or user feedback would be very appreciated. Please send feedback to: jamesmarkchan[at]gmail.com We also welcome feature request and or code contributions. https://gitlab.com/jamesmarkchan/jDiskMark/ Note: When doing a combined read and write operation the disk cache is not cleared automatically so the app must be restarted to avoid the cache from affecting read IO performance.
The Cocoa Benchmark
iBench is a benchmark for Mac OS X constituted by a suite of tests of real-world usage that allows you to check and compare Macintosh computers performance on integer and floating point workloads. iBench is compatible with both Intel and PowerPC Macs.
Ftop displays progress information for the open files in a Linux system. As processes read & write files, ftop displays data rates and time estimates. Its feature-rich interface is similar to top, and includes extensive run-time configuration options.
Battery monitoring and health tool.
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).
An easy to use JDBC benchmark that closely resembles the TPC-C standard for OLTP. RDBMS's presently supported include PostgreSQL, EnterpriseDB and Oracle.
HardInfo displays information about your hardware and operating system.
Wintel based platform system power management and analysis utilities.
Fast Fourier Transforms (FFT) for Multi-CPU (and RAM) Stress Testing. Shows detailed information about physical and logical processors in the system. Included CPU Benchmark feature for speed testing. Automatically utilizes and tests all CPU cores.
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/
Collectl is a light-weight performance monitoring tool capable of reporting interactively as well as logging to disk. It reports statistics on cpu, disk, infiniband, lustre, memory, network, nfs, process, quadrics, slabs and more in easy to read format.
