 * For **cryptonight-lite** it's **1 MB** or **2 MB** (lower power mode) per thread.

+By default, XMRig try choice optimal threads settings for current CPU with very estimated maximum CPU load 75% (`--max-cpu-usage=75`).

+-a, --algo=ALGO       cryptonight (default) or cryptonight-lite

+If you want use CryptoNight-Lite (AEON) you should specify this option `--algo=cryptonight-lite`. For cryptonight (Monero) it's option optional.

+-t, --threads=N       number of miner threads

+Manually specified number of threads. With `--safe` option this number can be automatically reduced to not to exceed the optimal thread count.

+-v, --av=N            algorithm variation, 0 auto select\n\
