We can speed-up dfa by improving memory accessibility etc. The following is the case that is particularly effective. $ ( seq 100000 | sed 's/$/ abcdefg hijklmn opqrstu vwxyz/'; echo XXXXXX. ) >in (Before) $ time -p env LC_ALL=C src/grep -vf in in real 39.20 user 20.35 sys 18.78 (After) $ time -p env LC_ALL=C src/grep -vf in in real 6.87 user 6.38 sys 0.48 Thanks, Norihiro0001-dfa-remove-unneeded-code.patch
