At 2.5G it is a couple of factors
Maybe we need to repack it (in particular, there have been a few occasions when mistakenly created branches were deleted or moved, which isn't optimal with the delta islands configuration). According to my notes, a full repack should be git repack --window=1250 --depth=250 -b -AdFfi (expect that to use more than 128 GB of memory and take over an hour of wall clock time even using all cores) and there was also a recommendation from Richard Earnshaw for weekly packing with git repack --window-memory=500m --window=250 --depth=50 -b -A -d -i for optimal efficiency. -- Joseph S.
