Examples
|
|
--------
|
|
|
|
Show disk I/O latency using the default values and the current directory, until interrupted
|
|
|
|
```
|
|
$ ioping .
|
|
4096 bytes from . (ext4 /dev/sda3): request=1 time=0.2 ms
|
|
4096 bytes from . (ext4 /dev/sda3): request=2 time=0.2 ms
|
|
4096 bytes from . (ext4 /dev/sda3): request=3 time=0.3 ms
|
|
4096 bytes from . (ext4 /dev/sda3): request=4 time=12.7 ms
|
|
4096 bytes from . (ext4 /dev/sda3): request=5 time=0.3 ms
