Zerocopy is a Rust library designed to make zero-cost memory manipulation both safe and effortless. It allows developers to reinterpret or convert raw byte sequences into structured types—and vice versa—without writing unsafe code directly. The crate provides safe abstractions for transmuting data while preserving Rust’s strict safety guarantees, removing the need for manual memory manipulation. Zerocopy introduces a suite of conversion traits such as TryFromBytes, FromBytes, IntoBytes, and FromZeros for defining how types can be safely constructed from or written to byte sequences. It also includes marker traits like KnownLayout, Immutable, and Unaligned to define type characteristics used in conversions. Complementing these traits are conversion macros that perform compile-time checks to ensure size and alignment safety, providing zero runtime overhead for unconditional casts.

PyLoris is a scriptable tool for testing a server's vulnerability to connection exhaustion denial of service (DoS) attacks. PyLoris can utilize SOCKS proxies and SSL connections, and can target protocols such as HTTP, FTP, SMTP, IMAP, and Telnet.

Marathon provides an integrated environment for test script creation and execution. Supported FW: Web, Java Swing/ Java FX. Currently, Marathon supports JRuby script models for recording the test scripts.Marathon test runner generates Allure test reports.Marathon allows for grouping of test cases.It also has an option of inserting modules while recording(in MarathonITE while recording). It allows tester to inset checklist while recording and also takes screen capture and annotate it in playing the test cases. Extraction of code into modules and inserting it is very easy using marathon.It has different themes of UI which attracts tester to do work on it. Object mapping is quite simple and configuring is very easy for tester to understand and do the work. Debugging of test scripts is also easy and has script console which takes selenium commands. Slow play of test cases is also available.It allows to create multiple fixtures for different types of tests.

nGrinder is a platform for stress tests that enables you to create test scripts, execute tests, monitor servers, and generate results simultaneously on the power of The Grinder. The open-source nGrinder offers easy ways to conduct stress tests by eliminating inconveniences and providing integrated environments. Our company NHN uses nGrinder to test several projects. Some have more than 100 million users.

Stochastic Performance Logic (SPL) serves for capturing performance assumptions. With SPL, it is possible to annotate Java functions with assumptions stating, for example, that the annotated function is at most three times slower than array copying. The assumption is then checked at build time in a similar way as standard unit testing. In other words, SPL is about introducing performance assert(). The advantage of SPL in comparison with other similar solutions includes following. SPL formulas uses well-defined logic and statistically sound testing (such as t-test). Next, SPL is aimed at automatic evaluation. And finally, SPL formulas uses relative comparisons (opposed to comparing against fixed time) to provide better portability.

We provide MATLAB and Verilog Models of GeAr, and previously proposed adders (ACA-I, ETAII, ACA-II and GDA) at http://sourceforge.net/projects/approxadderlib/ GeAr is a low latency Generic Accuracy Configurable Adder that provides a higher number of potential configurations compared to state-of-the-art approximate adders, thus enabling a high degree of flexibility and trade-off between performance and output quality. These MATALB and Verilog models can allow software programmer as well as hardware designers to evaluate their code and design. To the best of our knowledge, this is the first open-source library of approximate adders that facilitates reproducible comparisons and further research and development in this direction across various layers of design abstraction. This work is a result of collaborative effort between Chair for Embedded Systems (CES) at Karlsruhe Institute of Technology (KIT), Germany and Vision Image and Signal Processing (VISpro) Lab at SEECS-NUST, Pakistan.

PROCOL space-based framework for multi-core. Based on LighTS (http://lights.sourceforge.net/). More to come soon ...

Boest is an application for stress testing an SAP BusinessObjects Enterprise deployment. It launches a series of tests in parallel from which we can measure performance of the BOE system

jLlama is a desktop application to monitor servers over SSH. Any figure retrieved from the command line can be polled and graphed in real time. Out of the box, jLlama can graph CPU and Memory usage for Linux and Solaris servers.

This is a simple, modular PHP class designed to record execution time benchmarks throughout different parts of a script. Compatible with virtually any PHP script, the code can be added/removed quickly and with ease. Accurate to the microsecond.

Conductor is a Java based, multi-user platform for product agnostic testing. It runs under a web server, contains a UI for test configuration, and contains an optional thin test client.

Quite useful library for code diagnosis. As for now it can measure time of working for simple blocks of code, but features like loop or counters are developed.

Stand alone Java application used simulate a memory leak in order to generate profile signatures. The application has the ability to generate system (CPU) load in order to observe profile signature changes.

Hiper is an open-source command-line tool designed for statistical analysis of web performance and page load behavior during performance testing. The tool repeatedly loads a specified webpage multiple times and gathers detailed timing metrics in order to produce more reliable performance measurements than single-run benchmarks. By averaging data across multiple page loads, Hiper helps developers understand whether performance optimizations actually improve real-world page loading behavior. The tool relies on browser performance timing data to capture metrics such as DNS lookup time, TCP connection time, time to first byte, download duration, DOM readiness, and total page load time. Hiper runs from the command line and can be installed globally using Node.js package managers, making it simple to integrate into development or testing workflows.

This software provides PL/SQL packages for defining and measuring business tasks utilizing Oracle's extended SQL tracing mechanism.

JDistUnit is a test framework for distributed unit testing with Java (think "JUnit on multiple computers at once"), useful for load and stress testing. Features hot deployment of test cases to the remote test servers.
