Housekeeping
Introduced in GitLab 8.4.
The housekeeping function runs git gc
(man page) on the current
project Git repository.
git gc
runs a number of housekeeping tasks, such as compressing file
revisions (to reduce disk space and increase performance) and removing
unreachable objects which may have been created from prior invocations of
git add
.
You can find this option under your [Project] > Settings.
