I just went through this building my first bitcoin node on Umbrel. ended up switching from a 7200rpm spinner over to an SSD, made a world of difference! I had't thought of turning off the TOR, sounds like something I should think about. Does having TOR on make much of a difference BigFish (npub1xn9…vhwl) ?
If you run into trouble migrating data Beerborn (npub16up…nevp) let me know. I just did it a couple of times after doing the initial block sync, worked like a charm. they don't have docs for it on Umbrel, but it wasn't too bad if you're good on the command line.
