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...

...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.

Reads a PostgreSQL database log file, extracts the SQL statements and executes them in the same order and timing against another database server. Useful for performance tests with real-world workload.

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).

An online request replication tool, also a network traffic replay tool, fit for real testing, performance testing, stability testing, stress testing, load testing, smoke testing, etc

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.

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

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.

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.
