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

• ​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

• ​tiobench - Threaded I/O bench for Linux

  Tiobench is a file system benchmark especially designed to test I/O performance 
  with multiple running threads.
