Why are you using -A instead of -a ?

Could you run 'git count-objects -v' before and after a repack in such
cases as well?

Why are you using this?

This is even worse. 150G / 2M per pack = approx 75000 packs.
What you should be aiming for is a _single_ pack for best performances.
A couple packs is common and doesn't make much of a difference. A
hundred packs is getting a bit large. But 75000 packs is totally
insane.
