The other being a network socket in this case? But that socket might be two servers over? Meh, ideally they've optimized that as well.
So absolutely it is a network problem which means custom fiber?

I don't know enough about custom fiber to know whether that will help stretch past being network-bottlenecked — most NICs max out at 10 gigabits/second, but I've heard of faster ones. Eventually you might be able to make yourself disk-limited... Either way, backing up one file is probably easier than backing up a zillion files scattered around the filesystem.
