I am using a raspberry pi to download the archived version of the blockchain with parity. I've started parity with
parity -d /home/xxx/data/Ethereum --pruning archive --public-node
However, the synchronisation is running at 0-5 blocks per second. At this rate, it won't finish for 1-2 years.
Is there a setting that I can use to speed this up. For example, if I reduced the --max-peers to 10 would it speed up the synchronisation? Or is this an unachievable feat for a Pi?
