If switching databases would help, that would mean we're doing a lot of queries in getNextBuildOnPortBuilder, which would mean request.properties.getProperty involves a query. So that means we should: (a) only do the queries once for each set of build requests, and (b) use Deferred so the main thread isn't waiting for every query to finish. - Josh
