Hello,
I have tested metaphan4 with example files and different --nproc settings (no, 4, 40 threads). I do not see any performance difference here. Is this expected?
The bash script lokked like this (changing the --nproc settings in the tests):
#!bin/bash
date
metaphlan SRS014476-Supragingival_plaque.fasta.gz --input_type fasta --nproc 4 > SRS014476-Supragingival_plaque_profile.txt
date
This are the performance results: There is no difference in the duration of the jobs.
I would appreciate any comments on this.
Best regards,
–nproc 4
