The conversion to a sqlite database from the output of the dumptxoutset took I think 14 or 15 minutes. Querying that each time with a filter is pretty fast, maybe 30s? Prob depends on if the filter generates a large or small result.

The original dumptxoutset call itself, I didn't time it, I'm gonna guess 15+ mins also?

Hardware: it's a VPS but similar specs to a good laptop.
