Can you use jsonn/src instead?  https://github.com/jsonn/src

Also here is some ~/.gitconfig  for your smaller machine (I have more* below)
[pack]
        threads = 1
[core]
        bigFileThreshold = 5m
[transfer]
        unpackLimit = 10
[push]
        default = simple

I can do a full clone in 415MB and a --depth 1 in far less.




*  experiment with the commented out stuff
[pack]
        #windowMemory = 2m
        #packSizeLimit = 64m
        #deltaCacheSize = 2m
        #deltaCacheLimit = 25
        #packSizeLimit = 2m
        threads = 1
[core]
        #packedGitWindowSize = 2m
        #packedGitLimit = 2m
        #deltaBaseCacheLimit = 2m
        #compression = 1
        #loosecompression = 1
        bigFileThreshold = 5m
[transfer]
        unpackLimit = 10
[push]
        default = simple
