I forgot to mention that the apps we use (gerrit and cgit) to host our
git repos do read the repos directly from disk therefore I think that
performing a gc on the repos would provide a performance improvement
(CPU and memory utilization) to gerrit and cgit.  It might be
difficult to quantify how much of an improvement since both those apps
do some cacheing of the repo data.  Anyways I think there would be
other benefits of `git gc` over `gerrit repack -adf` besides just
recovering disk space.  -Khai
