Yell is a little command line utility playing a short tune on your speaker device. I mainly use it to yell the "sysop" on a remote machine. It could also be used as a notification for finished tasks (eg. make buildworld && yell).

This is a XMMS input plugin for playing .nsf and .hes audio files. It supports all internal sound channels and the extra sound channels found in the Konami VRC6, Konami VRC7, Namco 106, Nintendo MMC5, and Sunsoft FME-07 chips. The extra sound channel present in the Famicom Disk System is also emulated.

XymMS is an XMMS input plugin capable of playing Sega Genesis GYM files by rendering FM, DAC, and PSG signals through emulation of the YM2612 and SN76496 sound chips found in the video game console. It supports zlib compression and decompression, and other various settings for output quality, etc. You can compress and decompress files along with updating ID tags using the File Info window.

Bonnie: Filesystem Benchmark Program Bonnie tests the speed of file I/O using standard C library calls. It does reads and writes of blocks, testing for the limit of sustained data rate (usually limited by the drive or controller) and updates on a file (better simulating normal operating conditions and quite dependent on drive and OS optimisations). The per-character read and write tests are generally limited by CPU speed only on current-generation hardware. It takes some 35 SPECint92 to read or write a file at a rate of 1MB/s using getc() and putc(). The seek tests are dependent on the buffer cache size, since the fraction of disk blocks that fits into the buffer cache will be found without any disk operation and will contribute zero seek time readings. I.e. if the buffer cache is 16MB and the Bonnie test file is 32MB in size, then the seek time will come out as half its real value. The seek time includes rotational delay, and will thus always come out higher than specified for a drive.

This library provides a powerful but simple way to measure sofware performance. It provides both a framework for executing and analysing benchmarks and a set of driver functions that makes it easy to build and run benchmarks, and to analyse their results.

iperf is a tool for measuring the maximum TCP and UDP bandwidth along a path between two hosts. It allows the tuning of various parameters and UDP characteristics, and reports bandwidth, delay jitter, datagram loss. iperf was originally developed by NLANR/DAST. iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. iperf3 also a number of features found in other tools such as nuttcp and netperf, but were missing from iperf 2.x. iperf3 is not backwards compatible with iperf 2.x.

This is lmbench-3.0-a9, a (sometimes controversial) system performance measurement tool. lmbench is a suite of simple, portable, ANSI/C microbenchmarks for UNIX/POSIX. In general, it measures two key features: latency and bandwidth. lmbench is intended to give system developers insight into basic costs of key operations. You can go to /usr/local/lib/lmbench and do one of the following: make results (to run the benchmarks) make rerun (to rerun the benchmarks) make see (to see how you did)

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

Pybench is an extensible benchmark suite for Python.

RAMspeed is a command line utility to measure cache and memory performance of computer systems. It offers 18 cache and memory benchmarks for i386 and amd64 machines, though 6 only for alpha ones. There are *mark benchmarks such as INTmark, FLOATmark, MMXmark and SSEmark. They operate with linear (sequential) data streams passed through ALU, FPU, MMX and SSE units respectively. There are also *mem benchmarks such as INTmem, FLOATmem, MMXmem and SSEmem. These are supposed to illustrate how fast is actual read/write memory performance. There are also non-temporal versions of MMX and SSE benchmarks. They have been coded with special instructions to minimise cache pollution on memory reads and to eliminate it completely on memory writes. In addition, they operate with a built in aggressive data prefetching algorithm. In some cases, non-temporal MMXmark and SSEmark can deliver almost 100% of theoretical bandwidth while reading.
