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.

The Zinf audio player is a simple, but powerful audio player for Linux and Win32. It supports MP3, Ogg/Vorbis, WAV and Audio CD playback, with a powerful music browser, theme support and a download manager. It is based on the FreeA*p audio player which was developed by EMusic. The FreeA*p project was discontinued due to a trademark conflict and EMusic being acquired by Vivendi.

xmms-wavpack is a plugin for the multimedia player XMMS that plays audio files in the WavPack format, which supports lossless and lossy compression.

Dbench is a filesystem benchmark that generates load patterns similar to those of the commercial Netbench benchmark, but without requiring a lab of Windows load generators to run. It is now considered a de-facto standard for generating load on the Linux VFS.

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.

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.

Iozone: 'IO Zone' Benchmark Program Iozone tests the speed of sequential I/O to actual files. Therefore, this measurement factors in the efficiency of your machine's file system, operating system, C compiler, and C runtime library. It produces a measurement which is the number of bytes per second that your system can read or write to a file.

Iozone: 'IO Zone' Benchmark Program (older 2.1 version) Iozone tests the speed of sequential I/O to actual files. Therefore, this measurement factors in the efficiency of your machine's file system, operating system, C compiler, and C runtime library. It produces a measurement which is the number of bytes per second that your system can read or write to a file. This is the 2.1 version of iozone. The new 3.x+ versions of iozone have completely changed their testing methods, thus their output is useless in comparing with older statistics.

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.

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.
