It was about a year ago that I did that sync. I kept coming back to it day after day to see it crawl along.

Now I'm syncing my new node on clearnet and it's halfway done in a day. And I've been planning how I want it to run purely on Tor afterwards and it hit me. If you set up your config to only allow Tor connection, you'll be rate limited by the Tor network itself. And that's a good explanation for why it took so long.
