pathChirp is a new active probing tool for estimating the available bandwidth on a communication network path. Based on the concept of "self-induced congestion", pathChirp features an exponential flight pattern of probes we call a chirp. Packet chirps offer several significant advantages over current probing schemes based on packet pairs or packet trains. By rapidly increasing the probing rate within each chirp, pathChirp obtains a rich set of information from which to dynamically estimate the available bandwidth.

Framework to benchmark PHP scripts or function calls.

The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available for the *nix operating system. This software is designed to effectively carry out both qualitative and quantitative benchmarks in a clean, reproducible, and easy-to-use manner.

Randomio is a multithreaded disk i/o microbenchmark. It requires O_DIRECT, pread/pwrite, and pthreads.

SPP provides frequently updated RTT estimates using IP traffic already present in the network. SPP estimates the RTT between two measurement points without requiring precise time synchronisation between each point. SPP accurately estimates the RTT experienced by any application's traffic without needing modifications to the application itself or the routers along the path.

This stress test suite will stress a computer system in various selectable ways It was designed to exercise various physical subsystems of a computer as well as various operating system kernel interfaces.

Super Smack is a benchmarking, stress testing, and load generation tool for MySQL (and PostgreSQL). Super Smack was originally written by Sasha Pachev, and then hosted and maintained by Jeremy Zawodny.

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. Special features of thrulay include: * For TCP, ability to measure round-trip delay along with throughput * For UDP, ability to measure - one-way delay, with quantiles - packet loss - packet duplication - reordering * For UDP, the ability to send precisely positioned true Poisson streams (microsecond errors in sending times) * Human- and machine-readable output (ready to be fed to gnuplot)

TTCP is a benchmarking tool for determining TCP and UDP performance between 2 systems. The program was created at the US Army Ballistics Research Lab (BRL) and is in the public domain. Feel free to distribute this program but please do leave the credit notices in the source and man page intact. How to get TCP performance numbers: receiver sender host1% ttcp -r -s host2% ttcp -t -s host1 -n and -l options change the number and size of the buffers.

The Unix Benchmark Utility "ubench" is an attempt to introduce a single measure of perfomance among computer systems running various flavors of Unix operation system. The current development release tests only CPU(s) and memory. In the future releases there will be tests added for disk and TCP/IP. Ubench is taking advantage of multiple CPUs on an SMP system and the results will reflect that. o Ubench is executing rather senseless mathematical integer and floating-point calculations for 3 mins concurrently using several processes, and the result Ubench CPU benchmark. o Ubench will spawn about 2 concurrent processes for each CPU available on the system. This ensures all available raw CPU horsepower is used. o Ubench is executing rather senseless memory allocation and memory to memory copying operations for another 3 mins concurrently using several processes, and the result Ubench MEM benchmark.
