### Healing
Healing is enabled by default. The following configuration settings allow for more staggered delay in terms of healing. The healing system by default adapts to the system speed and pauses up to '1sec' per object when the system has `max_io` number of concurrent requests. It is possible to adjust the `max_delay` and `max_io` values thereby increasing the healing speed. The delays between each operation of the healer can be adjusted by the `mc admin config set alias/ max_delay=1s` and maximum concurrent requests allowed before we start slowing things down can be configured with `mc admin config set alias/ max_io=30` . By default the wait delay is `1sec` beyond 10 concurrent operations. This means the healer will sleep *1 second* at max for each heal operation if there are more than *10* concurrent client requests.

In most setups this is sufficient to heal the content after drive replacements. Setting `max_delay` to a *lower* value and setting `max_io` to a *higher* value would make heal go faster.

Example: The following settings will increase the heal operation speed by allowing healing operation to run without delay up to `100` concurrent requests, and the maximum delay between each heal operation is set to `300ms`.
```sh
~ mc admin config set alias/ heal max_delay=300ms max_io=100
~ mc admin config set alias/ heal max_sleep=300ms max_io=100
