This I can confirm, the auto-gc brought this down to 5.3G last night.

Still, this is a lot worse than ealier: On April 7th the total size of
.git/objects/ was just 1571M here - a day later things started to go
downhill.
Interesting. Do you graph the .git usage somehow, and do you have more data?
I believe that Salsa is still sending very suboptimal packs over the
network, which are then reused by the local Git.
'git gc --aggressive --keep-largest-pack' repacked the most recents
packs from last week MUCH more efficiently (1.6GB -> 12MB), which tends
to confirm this hypothesis.
'git gc --aggressive' is supposed to repack everything, but I'm not able
to run it on my computer anymore at this currently OOMs at >20GB RAM,
which means previous packs may stay fat and non-optimized forever.
It's a bit saddening nothing has happened about this while everybody
should have been aware this will not resolve by itself - but rather get
worse over time :(
I also see that files >50MB now get a warning at GitHub (before getting
rejected at >100MB), so with our data/CVE/list at 53MB we're starting to
hit all kinds of hard limits, confirming we have to do something sooner
than later.
Maybe this is something where the LTS Team can help with, let's wait for
the bookworm LTS handover to take place this week, and I'll try and
reach out to involved teams.
