Open Source C Performance Testing Software

sysbench is a scriptable multi-threaded benchmark tool based on LuaJIT. It is most frequently used for database benchmarks, but can also be used to create arbitrarily complex workloads that do not involve a database server. extensive statistics about rate and latency is available, including latency percentiles and histograms. Low overhead even with thousands of concurrent threads. sysbench is capable of generating and tracking hundreds of millions of events per second. New benchmarks can be easily created by implementing pre-defined hooks in user-provided Lua scripts. Can be used as a general-purpose Lua interpreter as well, simply replace #!/usr/bin/lua with #!/usr/bin/sysbench in your script. Execute events for this many seconds with statistics disabled before the actual benchmark run with statistics enabled. This is useful when you want to exclude the initial period of a benchmark run from statistics.

News: since 2015 we continue all related developments within Collective Knowledge Framework: http://github.com/ctuning/ck/wiki Alchemist plugin is a collection of plugins for GCC/LLVM for external and fine-grain code analysis and tuning. It is intended to to extract program properties for machine learning based optimization (see MILEPOST GCC); optimize programs at fine-grain level (such as unrolling, tiling, prefetching, etc); tune default optimization heuristic; gradually decompose program and detect performance or other anomalies; generate benchmarks particularly useful to train ML-based compilers. GCC plugin is licenced under GPLv3 licensed, while future LLVM plugins will be licensed under BSD license. Alchemist plugin is in a preliminary stage (based on MILEPOST ML plugin), so collaborations are very welcome!

A Perl-based benchmarking and load testing suite, with backend written in C. Based on apachebench, but extended with much more functionality. Currently released on CPAN as HTTPD::Bench::ApacheBench.

BP-Sim allows users to perform an extensive range of tests across the chain of payment services and thus identify potential causes of failures before launching payment systems into production. BP-Sim consists of following modules: BP-Source, BP-Host, BP-HSM and BP-SeeEMV. BP-Source and BP-Host are payment transaction simulators supporting formats as: APACS30, AS2805, many ISO8583 dialects, IFSF, SPDH, TCMP. Together with industry-standard cryptography, multi-platform support, configurable transaction load up to 2000 TPS. BP-Sim HSM module provides an adequate TCP/IP simulation of the Thales Hardware Security Mod. BP-SeeEMV simulates the steps involved in an EMV transaction that take place in the EMV terminal and the Issuer Server (when conducted online). Module can process a transaction one step at a time in step-by-step mode or to certain break-point.

DDMTestbed is a testbed that allows you to generate random instances and evaluate your proposed resolutive method measuring execution time, memory occupied and distance from the optimal solution. It has been written in C language.

Ingres Dynamic Playback is a tool to play back prerecorded SQL statements to do functional and stress testing on the Ingres Database. More information here: http://community.ingres.com/wiki/Dynamic_Playback

It's a integrated performance analysis tool with GUI, which is integrated with various utilities such as strace, Gcov, Gprof, proc etc which are open released and are for analyzing performance of linux system

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 framework that compares performance of different pieces of code. Available in four languages: c#.net (SharpKinoko), java (JKinoko), c (CKinoko) and c++ (CppKinoko)

A collection of library code and tools for application execution profiling and performance testing. You can create stopwatches to time select portions of your code. You can measure differences (often to sub-millisecond accuracy) between clocks on different machines. You can log application events in a .csv format for subsequent analysis. You can also generate CPU loading logs in a .csv format.

A multi threading management library

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

TCPCopy is a TCP stream replay tool to support real testing of Internet server applications. Although the real live flow is important for the test of Internet server applications, it is hard to simulate it as online environments are too complex. To support more realistic testing of Internet server applications, we develop a live flow reproduction tool - TCPCopy, which could generate the test workload that is similar to the production workload. Currently, TCPCopy has been widely used by companies in China. TCPCopy has little influence on the production system except occupying additional CPU, memory and bandwidth. Moreover, the reproduced workload is similar to the production workload in request diversity, network latency and resource occupation. TCPCopy consists of two parts, TCPCopy and intercept. While TCPCopyruns on the online server and captures the online requests, intercept runs on the assistant server and does some assistant work, such as passing response info to TCPCopy.

The goal of this project is to develop a framework to test and measure the performance of IEEE 802.11 based devices. Currently we aims to address the issues related to protocol conformance testing for a device.

The alio library can be dynamically pre-linked to existing executables and replaces file IO (i.e. calls to glibc's IO functions). This allows to gather statistics about IO, create IO trace files, or even implement a different IO behaviour (e.g. use separate IO servers to handle IO).

BEMAP (BEnchMarks for Automatic Parallelizer) is a benchmark used to measure performance for an automatic parallelizer. All OpenCL code benchmarks covered in this project are done step-by-step along with hand-tunning. Each tuning step executional time are measured in details with a comprehensive user interface and help option. The exact implementation in native code (C++) is also provided in each project folder for reference. By using these benchmarks, one may analyze: 1. How to tune/optimize the auto-parallelizer's compiler 2. Whether the appropriate optimization procedure is provided within the compiler This project is partially funded by the Department of the New Energy and Industrial Technology Development Organization (NEDO).

Base C/C++ library providing unit testing framework with integrated memory leak and buffer overrun detection.

Note: this tool has moved to github, this repository is not maintained any more. See https://github.com/turdusmerula/ftrace GScopeLog is a tool for instrumenting c++ code through gcc. The main purpose is to trace entry/exit point of functions. A status file may be generated to give overview of functions calls and timing informations with minimal impact on performances.
