OK, here's something else for you to try: core.deltabasecachelimit=0 pack.threads=2 pack.deltacachesize=1 With that I'm able to repack the small gcc pack on my machine with 1GB of ram using: git repack -a -f -d --window=250 --depth=250 and top reports a ~700m virt and ~500m res without hitting swap at all. It is only at 25% so far, but I was unable to get that far before. Would be curious to know what you get with 4 threads on your machine.
