Although the pack-file is just 1.7GB for me, not 3.7 like somebody said. Anyway, doing a git blame --incremental HEAD -- org.eclipse.debug.ui/plugin.xml > /dev/null on that thing (picked a random file that got modified in a recent commit) took something like 12 seconds, so this is certainly a perfectly fine test-case. Sadly, "git-gui blame" doesn't work in a bare git repository, so I had to do an ugly ln -s . .git to make git-gui happy, and that worked, and was pretty usable. Still, 12seconds should be something we can improve on. And yeah, the profile is pretty horrid: samples % app name symbol name 70307 20.9412 libc-2.5.so strlen 50925 15.1682 libz.so.1.2.3 (no symbols) 24295 7.2364 git tree_entry_interesting 19816 5.9023 libc-2.5.so memcpy 19569 5.8287 git tree_entry_extract 17693 5.2699 vmlinux memcpy_c 17032 5.0730 git assign_blame 16956 5.0504 git get_mode 12401 3.6937 git get_origin 11815 3.5191 git skip_uninteresting 10449 3.1123 git update_tree_entry 10359 3.0855 git find_pack_entry_one 7946 2.3667 git cmp_suspect 4572 1.3618 libc-2.5.so strncmp ... so I guess we need to find some more strlen's to remove ;) Linus - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
