Heads up for anyone playing with it soon, there's a relatively recent bug in LND that will slow neutrino sync to a crawl if you createwallet before it finishes (as doing so unintentionally triggers a full block by block rescan)
I reported it after noticing our Lightning.Pub flow wasn't working as expected in v19, we've implemented a temporary workaround though if you use our install script #1196941#1204143
