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 nostr:npub1xn9fxlmwj92svvllfkpcrvugkrx2ytfp9luw0w2n7r693jckay2sahvhwl ?
If you run into trouble migrating data nostr:npub16up8472yajrceaxq72yz4an7lggw0s6esgg7rm74k8fh3khsesjs6vnevp 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.
