From: Ben Peart <benpe...@microsoft.com> The reset (mixed) command unstages the specified file(s) and then shows you the remaining unstaged changes. This can make the command slow on larger repos because at the end it calls refresh_index() which has a single thread that loops through all the entries calling lstat() for every file.
If the user passes the --quiet switch, reset doesn�t display the remaining unstaged changes but it still does all the work to find them, it just doesn�t print them out so passing "--quiet" doesn�t help performance. This patch series will: 1) change the behavior of "git reset --quiet" so that it no longer computes the remaining unstaged changes. 2) add a new config setting so that "--quiet" can be configured as the default so that the default performance of "git reset" is improved. The performance benefit of this can be significant. In a repo with 200K files "git reset foo" performance drops from 7.16 seconds to 0.32 seconds for a savings of 96%. Even with the small git repo, reset times drop from 0.191 seconds to 0.043 seconds for a savings of 77%.
