mdtest is an MPI-coordinated metadata filesystem benchmark test that performs open/stat/close operations on files and directories and then reports achieved performance.

This is a network benchmark for DOS, OS/2 2.x, Windows NT/2000 and Unix. It measures the net throughput of a network via NetBIOS and/or TCP/IP protocols (Unix and DOS only support TCP/IP) using various different packet sizes. One instance has to run on one machine as a server process, another instance is used on another machine to perform the benchmark. When executed without arguments, the program will explain its usage.

Netperf is a serious networking performance evaluation tool being distributed under GPL by HP's Information Networks Division. Testing is done using a pair of programs: `netserver' (the server) and `netperf' (the measurement tool). Netperf allows control over a large number of test `variables'. Some of these are: * specification of desired confidence levels for the tests Netperf will warn the user if these levels were not achieved. * filling send buffers with specified data (to beat compression schemes) * specification of send/receive buffer alignments and data offsets * requesting CPU utilization and service demand calculations * specification of sizes of data to send Netperf can be used for measuring stream performance as well as round-trip performance.

NetPerfMeter is a network performance meter for the UDP, TCP, SCTP and DCCP transport protocols over IPv4 and IPv6. It simultaneously transmits bidirectional flows to an endpoint and measures the resulting flow bandwidths and QoS. The results are written as vector and scalar files. The vector files can e.g. be used to create plots of the results.

NetPIPE is a protocol independent performance tool that encapsulates the best of ttcp and netperf and visually represents the network performance under a variety of conditions. By taking the end-to-end application view of a network, NetPIPE clearly shows the overhead associated with different protocol layers. Netpipe answers such questions as: how soon will a given data block of size k arrive at its destination? Which network and protocol will transmit size k blocks the fastest? What is a given network's effective maximum throughput and saturation level? Does there exist a block size k for which the throughput is maximized? How much communication overhead is due to the network communication protocol layer(s)? How quickly will a small (< 1 kbyte) control message arrive, and which network and protocol are best for this purpose? For a paper fully describing NetPIPE and sample investigation of network performance issues using NetPIPE, see the homepage.

NoSQL Benchmark (nb) is a multi-threaded benchmark tool for evaluating main database performance metrics using OLTP-alike benchmarking against a specified workload. Features include: * benchmarking types: unlimited, time limited or maximum thread limited * different threads creation policies: at once or interleaved * key distribution supported: uniform, gaussian * key types supported: string, u32, u64 * CSV report file generation supported (for future plot generation) * single configuration file * workload tests are specified in percents against a total request count * supported database drivers: tarantool, leveldb (redis, memcached planned). * plotter tool (CSV to GNU Plot generation)

N-queens benchmark written in C. Includes base version and (optinal) distributed MPI version.

This program is a much more convient version of the ttcp program. It uses inetd (or simulates its behaviour) to start off the remote side program which will send/receive data. Both sides measure the time and number of bytes transfered. The local side will print the measures. The format of the output can be specified on the commandline.

nuttcp is a network performance measurement tool intended for use by network and system managers. Its most basic usage is to determine the raw TCP (or UDP) network layer throughput by transferring memory buffers from a source system across an interconnecting network to a destination system, either transferring data for a specified time interval, or alternatively transferring a specified number of bytes. nuttcp is based on nttcp, but have several useful features such as a server mode, rate limiting, multiple parallel streams, and timer based usage.

The octave-forge package is the result of The GNU Octave Repositry project, which is intended to be a central location for custom scripts, functions and extensions for GNU Octave. contains the source for all the functions plus build and install scripts. This is benchmark. The package contains code used to benchmark speed of Octave.
