(f6de00f6cec3831b8f334de7dbd1b59115627457), but I don't see any
performance boost. Rather the opposite.
Comparing with debian's grep 2.20-3, that includes your first patch to solve
this -P issue, 0001-grep-P-invalid-utf8-non-matching.patch:
grep -P asdf /usr/bin/* 12,42s user 0,12s system 99% cpu 12,545 total
src/grep -P asdf /usr/bin/* 14,37s user 0,12s system 99% cpu 14,492 total
Note that basic grep also slowdowns:
grep asdf /usr/bin/* 0,22s user 0,16s system 99% cpu 0,382 total
src/grep asdf /usr/bin/* 1,26s user 0,12s system 99% cpu 1,384 total
Cheers, and thanks for your work,
Santiago
