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.
