dada2 denoise-paired doubt

When I use the command qiime dada2 denoise-paired .. what is the meaning of ''–p-n-threads 10'' ??

qiime dada2 denoise-paired --i-demultiplexed-seqs /home/qiime2/dec2021/paired-end-demux.qza --p-trim-left-f 0 --p-trim-left-r 0 --p-trunc-len-f 260 --p-trunc-len-r 260 --o-table /home/qiime2/dec2021/table.qza –p-n-threads 10 --o-representative-sequences /home/qiime2/dec2021/rep-seqs.qza --o-denoising-stats /home/qiime2/dec2021/denoising-stats.qza


It is written in the plugin description:

--p-n-threads INTEGER The number of threads to use for multithreaded
processing. If 0 is provided, all available cores
will be used. [default: 1]

That's mean that provided number of threads will be used to process the job. The more threads are used, the faster the job will be implemented, but memory (RAM) requirements will also increase.
