= CPU : POV-RAY =

 * Persistence of vision raytracer (3D renderer)
 * 由於 Ray Tracing 的 3D 繪圖運算會消耗非常多 CPU 資源，因此我們經常使用 POV-RAY 來作為 CPU-intensive 的 Workload 模擬。

= Network : netcat =

 * 使用 netcat 搭配 dd 測試 TCP 與 UDP 的速度
{{{
==TCP==

[recive firstly]

ncat -l 60000 > /dev/null

[then send]

cat /dev/zero | ncat 140.110.X.X 60000

==UDP==

[recive firstly]

ncat -u -l 60000 > /dev/null

[then send]

cat /dev/zero | ncat -u 140.110.X.X 60000
}}}

== Database ==

 * [http://packages.debian.org/squeeze/sysbench sysbench] - Cross-platform and multi-threaded benchmark tool
{{{
Current features allow to test the following system parameters:

 * file I/O performance
 * scheduler performance
 * memory allocation and transfer speed
 * POSIX threads implementation performance
 * database server performance (OLTP benchmark)

Primarily written for MySQL server benchmarking, SysBench will be further 
extended to support multiple database backends, distributed benchmarks and 
third-party plug-in modules. 
}}}

== Multi-thread ==

 * [http://packages.debian.org/squeeze/tiobench tiobench] - Threaded I/O bench for Linux
{{{
Tiobench is a file system benchmark especially designed to test I/O performance 
with multiple running threads.
