I see the reason is the workaround in do_execute that turns on line-by-line matching for -i across the board - I got runtime confirmation by trying "<name>.*[rR][uU][sS][sS][iI][aA]" - the times were faster than for grep 2.5.1 with -i: 3.59user 2.95system 0:06.55elapsed
I'm not sure if the workaround is for the -i problem in UTF-8 locales discussed in http://savannah.gnu.org/bugs/?29391. This bug report really should be titled "--ignore-case very slow in grep 2.14" Zartaj ________________________________ From: GNU bug Tracking System <[email protected]> To: Z.
