Make git grep use threads when it is available. The results below are best of five runs in the Linux repository (on a box with two cores). With the patch: git grep qwerty 1.58user 0.55system 0:01.16elapsed 183%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+800outputs (0major+5774minor)pagefaults 0swaps Without: git grep qwerty 1.59user 0.43system 0:02.02elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+800outputs (0major+3716minor)pagefaults 0swaps And with a pattern with quite a few matches: With the patch: $ /usr/bin/time git grep void 5.61user 0.56system 0:03.44elapsed 179%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+800outputs (0major+5587minor)pagefaults 0swaps Without: $ /usr/bin/time git grep void 5.36user 0.51system 0:05.87elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+800outputs (0major+3693minor)pagefaults 0swaps In either case we gain about 40% by the threading.
