Description Jason W. Bacon freebsd_committer freebsd_triage 2022-01-04 17:36:01 UTC 
Diffing the attached files after uncompressing on FreeBSD 13.0:

FreeBSD coral.acadix  bacon ~ 1006: time diff temp1.fastq temp2.fastq > /dev/null
       73.13 real        72.66 user         0.02 sys

On a CentOS 7 VM running on the same host:

Linux centos7.local  bacon ~ 586: (pkgsrc): time diff temp1.fastq temp2.fastq  > /dev/null
0.779u 0.022s 0:00.80 98.7%     0+0k 0+0io 0pf+0w
