The Extended Module Player, or xmp, is a portable command-line module player
supports over 80 mainstream and obscure module formats from Amiga, Atari,
Acorn, Apple IIgs and PC.
xoscope is a digital oscilloscope using input from a sound card or EsounD
and/or a ProbeScope/osziFOX and will soon support Bitscope hardware.
Includes 8 signal displays, variable time scale, math, memory, measurements,
and file save/load.
ZynAddSubFX is a opensource software synthesizer capable of making
a countless number of instruments, from some common heard from
expensive hardware to interesting sounds that you'll boost to an
amazing universe of sounds.
The volume normalizer plugin is intended to change the volume of
playing songs to some level such that they all will basically sound
pretty much the same in terms of volume.
Filebench is quick to set up and use unlike many of the commercial
benchmarks which it can emulate. It is also a handy tool for
micro-benchmarking storage subsystems and studying the relationships of
complex applications such as relational databases with their storage
without having to incur the costs of setting up those applications,
loading data and so forth.
Filebench uses loadable workload personalities in a common framework to
allow easy emulation of complex applications upon file systems. The
workload personalities use a Workload Definition Language to define the
workload's model.
Flowgrind is an advanced TCP traffic generator for testing and
benchmarking Linux, FreeBSD, and Mac OS X TCP/IP stacks. In
contrast to similar tools like iperf or netperf it features a
distributed architecture, where throughput and other metrics are
measured between arbitrary flowgrind server processes.
GtkPerf is an application designed to test GTK+ performance. The point is to
create common testing platform to run predefined GTK+ widgets (opening
comboboxes, toggling buttons, scrolling text yms.) and this way define the speed
of device/platform.
glmark2 is a benchmark for OpenGL (ES) 2.0. It uses only the subset of the
OpenGL 2.0 API that is compatible with OpenGL ES 2.0.
What is Iperf?
While tools to measure network performance, such as ttcp,
exist, most are very old and have confusing options. Iperf
was developed as a modern alternative for measuring TCP
and UDP bandwidth performance.
Iperf is a tool to measure maximum TCP bandwidth, allowing
the tuning of various parameters and UDP characteristics.
Iperf reports bandwidth, delay jitter, datagram loss.
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.
