(In reply to parv from comment #4)
I should have also mentioned that above egrep were tested with 2 pairs of
locale configuration (time result is same enough) ...
# root user.
LANG=C.UTF-8
# Not root user.
LANG=en_US.UTF-8
LC_COLLATE=C
LC_CTYPE=en_US.UTF-8
LC_MESSAGES=en_US.UTF-8
LC_MONETARY=en_US.UTF-8
User CPU time of "egrep -i" improves with C locale ("env LANG=C LC_ALL=C egrep
-i ...") ...
38.24 real 36.44 user 0.61 sys # Just after loading RAM as mentioned in
#4.
44.32 real 38.10 user 0.59 sys # Successive runs ...
39.88 real 39.00 user 0.59 sys # ... after few minutes.
