Revision 22631473e0b7a33356587ba3e38a9b4cc4dba2f1 authored by Linus Torvalds on 10 August 2007, 16:51:58 UTC, committed by Junio C Hamano on 10 August 2007, 20:57:43 UTC
This trivial patch avoids re-hashing files that are already clean in the index. This mirrors what commit 0781b8a9b2fe760fc4ed519a3a26e4b9bd6ccffe did for "git add .", only for "git commit ." instead. This improves the cold-cache case immensely, since we don't need to bring in all the file contents, just the index and any files dirty in the index. Before: [torvalds@woody linux]$ time git commit . real 1m49.537s user 0m3.892s sys 0m2.432s After: [torvalds@woody linux]$ time git commit . real 0m14.273s user 0m1.312s sys 0m0.516s (both after doing a "echo 3 > /proc/sys/vm/drop_caches" to get cold-cache behaviour - even with the index optimization git still has to "lstat()" all the files, so with a truly cold cache, bringing all the inodes in will take some time).
