Blockchains don't scale. The fact that all nodes process all transactions means that the blockchain only goes as fast as the slowest node allowed on the network. If that's something like a Raspberry Pi, then that's as fast as the blockchain goes.
And that's okay! The upside is that the more people can run nodes, the more resilient the blockchain will be. It's much harder to break a 10,000-node blockchain where most nodes run on home computers all across the world than a 10,000-node blockchain where most nodes run in a few datacenters.
