ioping

Monitor I/O latency in real time. More information: https://github.com/koct9i/ioping.

• Show disk I/O latency using the default values and the current directory:
  ioping .
• Measure latency on /tmp using 10 requests of 1 megabyte each:
  ioping -c 10 -s 1M /tmp
• Measure disk seek rate on /dev/sdX:
  ioping -R {{/dev/sdX}}
• Measure disk sequential speed on /dev/sdX:
  ioping -RL {{/dev/sdX}}
