+### efficiency versus paranoia
+
+If you're paranoid enough to use mirrors, you should be paranoid enough to
+like the `receive.fsckObjects` setting we now default to :-) However, informal
+tests indicate a 40-50% CPU overhead from this.  If you don't like that,
+remove that line from the post-receive code.
+
+Please also note that we only set it on mirrors, and that too at the time the
+mirrored repo is *created*.  This means, when you start using your old "main"
+server as a mirror (see later sections on switching over to a mirror, etc.),
+it's repos do not have this setting.  Repos created by previous versions of
+gitolite also will not have this setting.
+
+Personally, I just set `git config --global receive.fsckObjects true`, since
+those servers aren't doing anything else anyway, and are idle for long
+stretches of time.  It's upto you what you want to do here.
