Right; it sounds to me like the real bug is that git-lfs isn't buffering writes to the network driver. Correct me if I'm wrong but if git-lfs was buffering its writes (or using sendfile) then Nagle's algorithm wouldn't matter.
It matters less often - it can still matter at the end of each write buffer. Larger write-buffers remove a lot of chances for this to happen.
If the application can buffer the entire file or use sendfile, probably best to disable Nagle's algorithm so the last packet goes out immediately. Nginx does this.
Another option is turning off Nagle's algorithm at the end of each transfer, and on at the start of the next, but this causes extra syscalls.
