+### JGit auto-configuration
+
+## Auto-disable `receive.autogc` option
+
+By JGit's default, `git-receive-pack` will run auto gc after receiving
+data from git-push and updating refs.
+
+Init step is added to auto-disable `receive.autogc` configuration option
+in `$gerrit_site/etc/jgit.config` file.
+
+## Auto-enable git wire protocol version 2
+
+By JGit's default, git wire protocol version 2 is disabled. Given, that git
+wire protocol version 2 on the server side is considered to be now very stable,
+activate it per default in init site program, so that gerrit sites benefit
+from improved fetch performance.
