This setting group is now moved to the Advanced settings in General settings.
These group of settings control Git repositories garbage collection. Garbage collection process will prune all loose objects, pack loose references and repack all reachable objects into new pack files and remove the old ones.
This is a block of parameters that determine when the garbage collection task is triggered for the clones of your repositories. The garbage collection task is invoked whenever the number of loose objects or packed files exceeds the set limit.

Loose objects are individual items that are not compressed into a Git pack file. The recommended default value is 2000.
Max packed files count
Set the maximum number of packed files that will be checked before the garbage collection is triggered. If the number of packed files count exceeds this setting, the garbage collection is activated. The recommended default value is 30.
