# Maximum CPU usage
|
||
|
|
|
||
|
|
Please read this document carefully, `max-threads-hint` (was known as `max-cpu-usage`) option is most confusing option in the miner with many myth and legends.
|
||
|
|
This option is just hint for automatic configuration and can't precise define CPU usage.
|
||
|
|
|
||
|
|
### Option definition
|
||
|
|
#### Config file:
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
...
|
||
|
|
"cpu": {
|
||
|
|
"max-threads-hint": 100,
|
||
|
|
...
|
||
|
|
},
|
||
|
|
...
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Command line
|
||
|
|
`--cpu-max-threads-hint 100`
|
||
|
|
|
||
|
|
### Known issues and usage
|
||
|
|
|
||
|
|
* This option has no effect if miner already generated CPU configuration, to prevent config generation use `"autosave":false,`.
|
||
|
|
* Only threads count can be changed, for 1 core CPU this option has no effect, for 2 core CPU only 2 values possible 50% and 100%, for 4 cores: 25%, 50%, 75%, 100%. etc.
|
||
|
|
* You CPU may limited by other factors, eg cache.
