--- Comment #23 from Alex Kozlov <ak@FreeBSD.org> ---
Just another data point:
Infamous dougb@ test which lead to revert of first gnu to bsdgrep conversion
attempt in 2010:

uname:
FreeBSD freefall.freebsd.org 14.0-CURRENT FreeBSD 14.0-CURRENT #0
main-n259006-a6346c02f64: Sun Nov 6 02:50:08 UTC 2022

[*]
https://www.FreeBSD.org/ports/INDEX-9.bz2

[*]: changed paths, number tries increased to 1000

results:
GNU grep
Elapsed time: 13 seconds

BSD grep
Elapsed time: 17 seconds

As you see, bsdgrep is still 30% slower than gnurep in this most common and
trivial case.
