I've seen a fair share of people requesting a "git gc" on their remote repos, since this seems not possible via the userinterface I'm here also asking if someone from Atlassian could please give this a litle swirl.
I have three repos in a shared workspace that cause my ocd to kick in:
blu********am/s*******vr.ar*********al.b***en.stl.git (currently showing as 288 MB)
blu********am/s*******vr.ar*********al.g**t.kgv.git (currently showing as 62 MB)
blu********am/s*******vr.ar*********al.g**t.stl.git (currently showing as 120.5 MB)
Hope this works, much appreciated!
