### 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.
