I have started a tezos node on my local machine in alphanet and it seems to take two hours to move head 12 days after downloading more than 800MB of data. The node seems to be actively getting data from peers. What is the total data size that will be downloaded till it bootstraps? How long does the bootstrapping normally take? Is there anyway to speed it up?
Alphanet size is currently around 13 GB. It is a very IO intensive process and it is recommended you use SSD where it it should take less than 4 hours to complete.
There isn't a commonly used quicksync for alphanet, but mainnet quicksync files can be found here https://www.tzdutch.com/quicksync/
