(In reply to Matteo Riondato from comment #15)
If this still occurs with /usr/bin/bsdgrep in 12.x, I think this is a
duplication.
However, I continue to feel that in 12.3-STABLE the performance of concurrent
storage usage by multiple processes has been poor...
> /usr/bin/time -l cat access_log.txt | grep -F -v -f exclude_ips.txt > output.log

Thus, this is reading and writing at the same time.
Doesn't it matter?
