 ## Usage
-The preferred way to configure the miner is the [JSON config file](src/config.json) as it is more flexible and human friendly. The [command line interface](https://xmrig.com/docs/miner/command-line-options) does not cover all features, such as mining profiles for different algorithms. Important options can be changed during runtime without miner restart by editing the config file or executing API calls.

+Use 1GB hugepages for RandomX dataset (Linux only). Enabled (`true`) or disabled (`false`). It gives 1-3% speedup.

Usually don't need change this option, this option useful for some rare cases when miner can't detect hardware AES, but it available. If you force enable this option, but your hardware not support it, miner will crash.
