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.

wrk is a modern, command-line HTTP benchmarking tool engineered for high performance, capable of generating substantial load using a single multi-core CPU by leveraging multithreading and scalable event notification systems. An optional LuaJIT script can perform HTTP request generation, response processing, and custom reporting. Details are available in SCRIPTING and several examples are located in scripts. The machine running wrk must have a sufficient number of ephemeral ports available and closed sockets should be recycled quickly. To handle the initial connection burst the server's listen(2) backlog should be greater than the number of concurrent connections being tested.

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.

Microstate Accounting is a way to determine exactly where a thread is spending its time. This project provides Linux kernel patches to implement microstate accounting.

I/O performance Analysis Tool

Utility for quick performance testing of main system components: disks, CPU and memory. Initially was designed to detect problems in virtual environment. Windows only (XP/2003 and later).

ArchC is an open-source architecture description language based on SystemC. Its goal is to provide designers with a tool to evaluate new ideas in processor and ISA design, memory hierarchy, etc. and other aspects of computer architecture research.

BEYE (Binary EYE) is a free, portable, advanced file viewer with built-in editor for binary, hexadecimal and disassembler modes. It contains a highlight AVR/Java/i86-AMD64/ARM-XScale/PPC-64 and other disassembler, full preview of MZ,NE,PE,ELF and other.

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.

swet (sustained workload & efficiency test) is a portable benchmark for POSIX and BSD operating systems with multi-thread and multi-process capabilities and flexible, powerful report options.

curl-benchmark is an open-source tool written in C-language that generates multiple and simultaneous HTTP/HTTPS requests and returns data for performance analysis.

Real time micro benchmark multi-lingual suite (RTMB) provides a good way to measure the deterministic quality of hardware, an operating system, or a Java Virtual Machine. RTMB consists of benchmarks in C, C++ and Java

Simple tool to parse the contents of /proc or /sys entries and graph their values. An oscillosope for software types. Intended for developers, admins or the curious to understand the performance and behaviour of their systems.

A generic, vendor-independent open-source application to determine the performance of a pub-sub infrastructure.

The Flexible Filesystem Benchmark (FFSB) is a cross-platform filesystem performance measurement tool. It uses customizable profiles to measure of different workloads, and it supports multiple groups of threads across multiple filesystems.

A 3D benchmark comparing the different features / extensions of OpenGL. Made for the Linux operating system, but is portable to any other OS that SDL supports.

Open System Testing Architecture - a distributed software testing architecture designed around CORBA. The current toolset has the capability of performing scripted Web (HTTP and HTTPS) heavy load tests with performance measurements from Win32 platforms.

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

benchIO is a multi-platform multi-function benchmark for I/O subsystems. It's written in ANSI C compatible with the POSIX standard

Bertha is an I/O benchmark tool for high-end storage subsystems. Based on Tim Bray's Bonnie benchmark tool with three enhancements: 1)it generates far more I/O, 2)it offers a facility to replay I/O transactions”, and 3)extensive metrics reporting.

A program to draw (and save the results to files) a diagramm that shows the execution time of a programm, which does some floating point calculations, in dependency of the number of used threads. It saves the result as a gnuplot file and a CSV file.
